GENERAL DESCRIPTION
The HMC1144 is a gallium arsenide (GaAs), pseudomorphic
high electron mobility transfer (pHEMT), monolithic microwave
integrated circuit (MMIC), distributed power amplifier that
operates from 35 GHz to 70 GHz. In the lower band of 35 GHz to
50 GHz, the HMC1144 provides 19 dB (typical) of gain, 28 dBm
output IP3, and 19 dBm and 19.5 dBm, respectively, of output
P1dB gain compression. In the upper band of 50 GHz to 70 GHz,
the HMC1144 provides 19 dB (typical) of gain, 32 dBm output
IP3, and 21 dBm of output power at 1 dB gain compression.
The HMC1144 requires 320 mA from a 4 V supply. The
HMC1144 amplifier inputs/outputs are internally matched to
50 Ω, facilitating integration into multichip modules (MCMs).
All data is taken with the chip connected via two 0.025 mm (1 mil)
wire bonds of 0.076 mm (3 mil) minimal length.
