Supply Voltage: +10 V @ 400 mA
50 Ohm Matched Input/Output
Die Size: 2.89 x 1.55 x 0.1 mm Functional Diagram General Description
The HMC797A is a GaAs MMIC pHEMT Distributed
Power Amplifier which operates between DC and 22
GHz. The amplifier provides 15 dB of gain, +29 dBm
of output power at 1 dB gain compression, +31 dBm
of saturated output power, and 23% PAE while requiring 400 mA from a +10 V supply. With up to +41 dBm
of output IP3, the HMC797A is ideal for high linearity applications in military and space as well as test
equipment where high order modulations are used.
This versatile PA exhibits a positive gain slope from 2
to 20 GHz making it ideal for EW, ECM, Radar and test
equipment applications. The HMC797A amplifier I/Os
are internally matched to 50 Ohms facilitating integration into Multi-Chip-Modules (MCMs). All data is taken
with the chip connected via two 0.025 mm (1 mil) wire
bonds of minimal length 0.31 mm (12 mils). Electrical Specifications, TA = +25° C, Vdd = +10V, Vgg2 = +3.5V, Idd = 400 mA*
