Rev A2 DS071207 RF3196 Theory of Operation Overview Building on previous generations of PowerStar® modules, the RF3196 has integrated Power Control with additional features such as VBATT tracking, and a power flattening circuit that reduces power and current variation into mismatch conditions. Theory of Operation The type of power control used in the RF3196 is a closed loop method that regulates the collector voltage of the amplifier while the stages are held at a constant bias. As the required output power is decreased from full power down to minimum PCLs, the collector voltage is also decreased. This process is repeatable and enables the user to implement a single point calibration, thereby increasing production by saving valuable time in the factory. The basic circuit is shown below in Figure 1. VBATT + VRAMP + 3 dB BW 300 kHz Saturation Detector H(s) VCC RF IN RF OUT TX ENABLE Figure 1. Power Control Circuit Output power does not vary due to supply voltage under normal operating conditions if VCC is sufficiently lower than VBATT. Regulating the collector voltage to the PA essentially eliminates voltage sensitivity. This covers most cases where the PA will be operated. However, as the battery discharges and approaches its lower voltage range, the maximum output power from the PA will also drop slightly. In this case it is important to decrease VRAMP to prevent the power control circuitry from inducing switching transients. These transients occur as a result of the control loop slowing down and not regulating power in accordance with VRAMP.. In the RF3196, is a VBATT tracking circuit that reduces the level of VRAMP as the battery voltage decreases. The limiter is integrated into the CMOS controller and requires no additional input from the user. In the circuit, a feedback loop is implemented that compares VBATT to VCC and produces a correction so that VRAMP is decreased. This prevents the switch transistor from being driven into saturation and inducing switching transients. In addition to the VBATT tracking circuit, the RF3196 has an integrated power flattening circuit that reduces the amount of current variation when a mismatch is presented to the output of the PA. When a mismatch is presented to the output of the PA, its output impedance is varied and could present a load that will increase output power. As the output power increases, so does current consumption. The current consumption can become very high if not monitored and limited. The power flattening circuit, like the VBATT tracking circuit, is also integrated onto the CMOS controller and requires no input from the user.

The power flattening circuit monitors current through an internal sense resistor. As the current changes, the loop is adjusted in order to maintain current. The result is flatter power and reduced current into mismatch. When compared to the RF3166, the RF3196 shows less current variation and has less power variation. Below, in Figure 2, is the power variation comparison.

Rev A2 DS071207 RF3196 The power control functionality provides 50dB continuous control range and 70dB total control range, using a DAC compatible analog voltage input referred to as VRAMP. The timing of the control signals is important for maintaining transient performance and superior isolation between the bursts. To ensure that the part ramps up properly, a timing diagram is provided below in Figure 4. It is important that ramping begins at least 2us after TXEN goes high. An offset voltage of 0.26V provides the greatest dynamic range for the best transient performance. 2.9 V to 4.2 V VBATT 2.5V BandSel 0 to 5 dBm RF Drive > 1.8V TX_Enable Vramp ends 2us before Tx_Enable Vramp starts 2us after Tx_Enable 0.26 to 2.1 V VRAMP Power On Sequence: The Power Down sequence is in opposite order of the Power On Sequence Apply VBATT Apply Band Select Apply RF drive Apply TX_Enable & VRAMP in unison Figure 4. RF3196 Timing Diagram As described in the above figure, VBATT is applied first to provide bias to the silicon control chip. Then the RF drive is applied. Finally, when TX_ENABLE is high, the VRAMP signal is held at constant 0.26V, and 2uS later, VRAMP begins to ramp up. The shape of VRAMP is important for maintaining the switching transients. The basic shape of the ramping function should be the first 90° of a raised sine function. This is shown in Equation 1 where A is the desired peak power in mW, B is the minimum output power of the power amplifier in mW, K determines the duration of the ramp, and t is time. The down-ramp function uses the same equation except a cosine function is used in the place of the sine function. The exponent “n” determines the steepness of the ramp and is typically set to 5. n P OUT ( mW ) = ( A – B ) ⋅ ( sin ( Kt ) ) + B (Eq. 1) The value of K is calculated using Equation 2. π K = -------------------2 ⋅ t ramp (Eq. 2) The Ramp synthesis tool provided by RFMD generates the ramp profiles automatically. It will generate ramps for all power levels and output the waveform for 8, 10, and 12 bit DACs in decimal, voltage, or hex formats.

Thermal Pad and Via Design Thermal vias are required in the PCB layout to effectively conduct heat away from the package. The via pattern has been designed to address thermal, power dissipation and electrical requirements of the device as well as accommodating routing strategies. The via pattern used for the RFMD qualification is based on thru-hole vias with 0.203mm to 0.330mm finished hole size on a 0.5mm to 1.2mm grid pattern with 0.025mm plating on via walls. If micro vias are used in a design, it is suggested that the quantity of vias be increased by a 4:1 ratio to achieve similar results.
