INA-32063 Applications Information Introduction The INA-32063 is a +3 volt silicon RFIC amplifier that is designed with a two stage internal network to provide a broadband gain and 50 Ω input and output impedance. With a typical +4.8 dBm P-1 dB compressed output power at 1900 MHz, for only 20 mA supply current. The broad bandwidth, INA-32063, is well suited for amplifier applications in mobile communication systems. A feature of the INA-32063 is a positive gain slope over the 1–2.5 GHz range that is useful in many satellite-based TV and datacom systems. In addition to use in buffer and driver amplifier applications in the cellular market, the INA-32063 will find many applications in battery operated wireless communication systems. Operating Details The INA-32063 is a voltage-biased device that operates from a +3 volt power supply with a typical current drain of 20 mA. All bias regulation circuitry is integrated into the RFIC. Figure 10 shows a typical implementation of the INA-32063. The supply voltage for the INA-32063 must be applied to two terminals, the Vd pin and the RF Output pin. 32 Gnd1 Gnd1 RF Output RFC Vd RF Input Cblock Figure 10. Basic Amplifier Application. Blocking capacitors are normally placed in series with the RF Input and the RF Output to isolate the DC voltages on these pins from circuits adjacent to the amplifier. The values for the blocking and bypass capacitors are selected to provide a reactance at the lowest frequency of operation that is small relative to 50 Ω. Cbypass Gnd 1 Gnd 2 VIA Figure 12. INA-32063 Potential Ground Loop. Gnd 1 VIA Gnd 2 VIA Example Layout for 50 Ω Output Amplifier Figure 13. INA-32063 Suggested Layout. An example layout for an amplifier using the INA-32063 with 50 Ω input and 50 Ω output is shown in Figure 11. At least one ground via should be placed adjacent to each ground pin to assure good RF grounding. Multiple vias are used to reduce the inductance of the path to ground and should be placed as close to the package terminals as practical. Gnd 1 RF Input 50 Ω Gnd 2 50 Ω RF Output and Vd Gnd 1 Figure 11. RF Layout. Cout Gnd2 The power supply connection to the RF Output pin is achieved by means of a RF choke (inductor). The value of the RF choke must be large relative to 50 Ω in order to prevent loading of the RF Output. The supply voltage end of the RF choke is bypassed to ground with a capacitor. If the physical layout permits, this can be the same bypass capacitor that is used at the Vd terminal of the amplifier. are used to bring the ground to the topside of the circuit where needed. The performance of INA-32063 is sensitive to ground path inductance. The two-stage design creates the possibility of a feedback loop being formed through the ground returns of the stages, Gnd 1 and Gnd 2. This example uses a microstripline design (solid groundplane on the backside of the circuit board). The circuit board material is 0.031-inch thick FR-4. Plated through holes (vias) The effects of the potential ground loop shown in Figure 12 may be observed as a “peaking” in the gain versus frequency response, an increase in input VSWR, or even as return gain at the input of the INA-32063. Figure 14 shows an assembled amplifier. The +3 volt supply is fed directly into the Vd pin of the 6 INA-32063 and into the RF Output pin through the RF choke (RFC). Capacitor C3 provides RF bypassing for both the Vd pin and the power supply end of the RFC. Capacitor C4 is optional and may be used to add additional bypassing for the Vd line. A well-bypassed Vd line is especially necessary in cascades of amplifier stages to prevent oscillation that may occur as a result of RF feedback through the power supply lines. A convenient method for making RF connection to the demonstration board is to use a PCB mounting type of SMA connector (Johnson 142-0701-881, or equivalent). These connectors can be slipped over the edge of the PCB and the center conductor soldered to the input and output lines. The ground pins of the connectors can be soldered to the ground plane on the backside of board. C1 C2 32 For this demonstration circuit, the value chosen for the RF choke was 120 nH (Coilcraft 1008CS-221, TOKO LL2012 -F or equivalent). All of the blocking and bypass capacitors are 100 pF. The gap in the output transmission line was bridged using copper foil cut to size. These values provide excellent amplifier performance from under 50 MHz through 2.4 GHz. Larger values for the choke and capacitors can be used to extend the lower end of the bandwidth. Since the gain of the INA-32063 extends down to DC, the frequency response of the amplifier is limited only by the values of the capacitors and choke. INA-3XX63 DEMO BOARD RFC C3 C4 Vd Figure 14. Assembled Amplifier. PCB Materials Typical choices for PCB material for low cost wireless applications are FR-4 or G-10 with a thickness of 0.025 (0.635 mm) or 0.031inches (0.787 mm) A thickness of 0.062 inches (1.574 mm) is the maximum that is recommended for use with this particular device. The use of a thicker board material increases the inductance of the plated through vias used for RF grounding and may deteriorate circuit performance. Adequate grounding is needed not only to obtain maximum amplifier performance but also to reduce any possibility of instability. Phase Reference Planes The positions of the reference planes used to measure S-Parameters for this device are shown in Figure 15. As seen in the illustration, the reference planes are located at the point where the package leads contact the test circuit. REFERENCE PLANES TEST CIRCUIT Figure 15. Phase Reference Planes.

This layout provides ample allowance for package placement by automated assembly equipment without adding pad parasitics that could impair the high frequency performance of the INA-32063.

Statistical Parameters Several categories of parameters appear within this data sheet. Parameters may be described with values that are either “minimum or maximum,” “typical,” or “standard deviations.” The values for parameters are based on comprehensive product characterization data, in which automated measurements are made on a large number of parts taken from 3 non-consecutive process lots of semiconductor wafers. The data derived from product characterization tends to be normally distributed, e.g., fits the standard “bell curve.” Parameters considered to be the most important to system performance are bounded by minimum or maximum values. For the INA-32063, these parameters are: Power Gain (|S21| 2 ) and the Device Current (Id). Each of these guaranteed parameters is 100% tested. Values for most of the parameters in the table of Electrical Specifications that are described by typical data are the mathematical mean (µ), of the normal distribution taken from the characterization data. For parameters where measurements or mathematical averaging may not be practical, such as S-parameters or Noise Parameters and the performance curves, the data represents a nominal part taken from the “center” of the characterization distribution. Typical values are intended to be used as a basis for electrical design. To assist designers in optimizing not only the immediate circuit using the INA-32063, but to also optimize and evaluate trade-off that affect a complete wireless system, the standard deviation (σ) is provided for many of the Electrical Specifications parameters (at 25°C) in addition to the mean. The standard deviation is a measure of the variability about the mean. It will be recalled that a normal distribution is completely described by the mean and standard deviation. Standard statistics tables or calculations provide the probability of a parameter falling between any two values, usually symmetrically located about the mean. Referring to Figure 17 for example, the probability of a parameter being between ±1σ is 68.3%; between ±2σ is 95.4%; and between ±3σ is 99.7%. 68% 95% 99% -3σ -2σ -1σ Mean +1σ +2σ (µ), typ +3σ Parameter Value Figure 17. Normal Distribution. SMT Assembly Reliable assembly of surface mount components is a complex process that involves many material, process, and equipment factors, including: method of heating (e.g., IR or vapor phase reflow, wave soldering, etc.) circuit board material, conductor thickness and pattern, type of solder alloy, and the thermal conductivity and thermal mass of components. Components with a low mass, such as the SOT-363 package, will reach solder reflow temperatures faster than those with a greater mass. The INA-32063 has been qualified to the time-temperature profile shown in Figure 18. This profile is representative of an IR reflow type of surface mount assembly process. After ramping up from room temperature, the circuit board with components attached to it (held in place with solder paste) passes through one or more preheat zones. The preheat zones increase the temperature of the board and components to prevent thermal shock and begin evaporating solvents from the solder paste. The reflow zone briefly elevates the temperature sufficiently to produce a reflow of the solder. The rates of change of temperature for the ramp-up and cool down zones are chosen to be low enough to not cause deformation of the board or damage to components due to thermal shock. For more information on mounting considerations for packaged microwave semiconductors 8 please refer to Agilent application note AN-A006. These parameters are typical for a surface mount assembly process for the INA-32063. As a general guideline, the circuit board and components should only be exposed to the minimum temperatures and times necessary to achieve a uniform reflow of solder. Electrostatic Sensitivity RFICs are electrostatic discharge (ESD) sensitive devices. Although the INA-32063 is robust in design, permanent damage may occur to these devices if they are subjected to high-energy electrostatic discharges. Electrostatic charges as high as several thousand volts (which readily accumulate on the The INA-32063 is an ESD Class 1 device. Therefore, proper ESD precautions are recommended when handling, inspecting, and assembling these devices to avoid damage. 250 TMAX TEMPERATURE (°C) 200 150 For more information on Electrostatic Discharge and Control refer to Agilent application note AN-A004R.
