GENERAL DESCRIPTION
The HMC637BPM5E is a gallium arsenide (GaAs), monolithic
microwave integrated circuit (MMIC), pseudomorphic high
electron mobility transistor (pHEMT), cascode distributed
power amplifier. The device is self biased in normal operation
and a 3.5 dB noise figure, while requiring 345 mA from a 12 V
supply voltage (VDD). Gain flatness is excellent from dc to 7.5 GHz
at 0.5 dB typical, making the HMC637BPM5E ideal for military,
space, and test equipment applications. The HMC637BPM5E
also features inputs/outputs (I/Os) that are internally matched to
50 Ω, housed in a RoHS-compliant, 5 mm × 5 mm, premolded
cavity, lead frame chip scale package (LFCSP), making the device
compatible with high volume, surface-mount technology (SMT)
assembly equipment.
and features optional bias control for quiescent current (IDQ
)
adjustment and for second-order intercept (IP2) and third-order
intercept (IP3) optimization. The amplifier operates from dc to
7.5 GHz, providing 15.5 dB of small signal gain, 28 dBm output
power at 1 dB gain compression, a typical output IP3 of 39 dBm,
