General Description
• Test Instrumentation
The HMC-C045 is a GaAs MMIC pHEMT Low Noise
Amplifier in a miniature, hermetic module which
operates between 1.8 and 4.2 GHz. This high dynamic
range low noise amplifier module provides 26 dB of
gain, sub-2 dB noise figure and up to +26 dBm of
output IP3 while operating from a single positive
supply between +8V and +15V. The amplifier I/Os are
internally matched to 50 Ohms and DC blocked for
robust performance. The module features removable
coaxial connectors which can be detached to allow
direct connection of the I/O pins to a microstrip or
coplanar circuit.
