AMMC-6345 20 – 45 GHz Driver Amplifier Data Sheet Chip Size: 2500 x 1150 µm (100 x 69 mils) Chip Size Tolerance: ± 10µm (±0.4 mils) Chip Thickness: 100 ± 10µm (4 ± 0.4 mils) Pad Dimensions: 100 x 100 µm (4 ± 0.4 mils) Description Features The AMMC-6345 MMIC is a broadband medium power amplifier designed for use in driving stage for transmitters that operate in various frequency bands between 20GHz and 45GHz. It can be used as a driver stage for the AMMC-6425, 6430 and 6440 (18-27GHz, 25-32GHz and 37-42GHz) 1W MMIC power amplifiers when linear operation is required. At 40GHz, it provides 24dBm of output power (P-1dB), 20dB of gain, and a 32 dBm output third order intercept (OIP3). The device has input and output matching circuitry for use in 50 Ω environments. The AMMC-6345 integrates a temperature compensated RF power detection circuit that enables power detection of 0.8V/W at 40GHz. The device operates on 5V for current supply (negative voltage only needed for Vg). It is fabricated in a PHEMT process for exceptional power and gain performance. For improved reliability and moisture protection, the die is passivated at the active areas. • Wide frequency range: 20 - 45 GHz • High gain: 20 dB • Power: @40 GHz, P-1dB=24 dBm • Highly linear: OIP3=32dBm • Integrated RF power detector • 5.0 Volt, -0.55 Volt, 480mA operation Applications • Microwave Radio systems • Satellite VSAT and DBS systems • LMDS & Pt-Pt mmW Long Haul • 802.16 & 802.20 WiMax BWA • WLL and MMDS loops • Commercial grade military • Can be driver amplifier for the AMMC-64xx power amplifiers AMMC-6345 Absolute Maximum Ratings[1] Symbol Vd Parameters/Conditions Positive Drain Voltage Units V Min.

Recommended quiescent DC bias condition for optimum power and linearity performances is Vd=5 volts with Vg set for Id=480 mA. For high gain applications, the AMMC-6345 can be biased at Vd=3V. Minor improvements in performance are possible depending on the application. The drain bias voltage range is 3 to 5.5V. A single DC gate supply connected to Vg will bias all gain stages. Muting can be accomplished by setting Vg to the pinch-off voltage Vp. The backside of the MMIC chip is RF ground. For microstrip applications the chip should be attached directly to the ground plane (e.g. circuit carrier or heatsink) using electrically conductive epoxy[1]. An optional output power detector network is also provided. The differential voltage between the Det-Ref and Det-Out pads can be correlated with the RF power emerging from the RF output port. The detected voltage is given by : V = (V ref − V det )− V ofs V where ref is the voltage at the DET _ R port, V det is a voltV age at the DET _ O port, and ofs is the zero-input-power offset voltage. There are three methods to calculate : V 1. ofs can be measured before each detector measurement (by removing or switching off the power source and measuring ). This method gives an error due to temperature drift of less than 0.01dB/50°C. V 2. ofs can be measured at a single reference temperature. The drift error will be less than 0.25dB. V 3. ofs can either be characterized over temperature and stored in a lookup table, or it can be measured at two temperatures and a linear fit used to calculate at any temperature. This method gives an error close to the method #1. The RF ports are AC coupled at the RF input to the first stage and the RF output of the final stage. No ground wired are needed since ground connections are made with plated through-holes to the backside of the device. For best performance, the topside of the MMIC should be brought up to the same height as the circuit surrounding it. This can be accomplished by mounting a gold plate metal shim (same length and width as the MMIC) under the chip which is of correct thickness to make the chip and adjacent circuit the same height. The amount of epoxy used for the chip and/or shim attachment should be just enough to provide a thin fillet around the bottom perimeter of the chip or shim. The ground plain should be free of any residue that may jeopardize electrical or mechanical attachment. The location of the RF bond pads is shown in Figure 12. Note that all the RF input and output ports are in a Ground-Signal configuration. RF connections should be kept as short as reasonable to minimize performance degradation due to undesirable series inductance. A single bond wire is normally sufficient for signal connections, however double bonding with 0.7 mil gold wire or use of gold mesh[2] is recommended for best performance, especially near the high end of the frequency band. Notes: 1. Ablebond 84-1 LM1 silver epoxy is recommended. 2.
