AMMC-5040 - 1

AMMC-5040 20-GHz to 45-GHz GaAs Amplifier Data Sheet The AMMC-5040 is a high gain broadband amplifier designed for both military applications and commercial communication systems. This four-stage amplifier has input and output matching circuitry for use in 50- environments. It is fabricated using PHEMT integrated circuit structures that provide exceptional broadband performance. The backside of this chip is both RF and DC ground. This simplifies the assembly process and reduces assembly related performance variations and costs. For improved reliability and moisture protection, the die is passivated at the ­active areas. This MMIC is a cost effective alternative to hybrid (discrete-FET) amplifiers that require complex tuning and assembly process. Chip Size: Chip Size Tolerance: ±10 μm (±0.4 mils) Chip Thickness: Frequency range: 20 GHz–45 GHz High gain: 25 dB Gain flatness: ±1.5 dB Return loss: Broadband gain block Broadband driver amplifier Point-to-point radio LMDS EW Instru

AMMC-5040 - 10

Data Sheet Biasing and Operation The recommended DC bias condition for the AMMC-5040 is with all four drains connected to a single 4.5V supply and all four gates connected to an adjustable negative voltage supply as shown in Figure 15. The gate voltage is adjusted for a total drain supply current of typically 300 mA. Figure 1 thorugh Figure 12 can be used to help estimate the minimum drain voltage and current necessary for a given RF gain and output power. As shown in Figure 13, the second, third, and fourth stage DC drain bias lines are connected internally and therefore require only a...
