General Description
The HMC635LC4 is a GaAs PHEMT MMIC Driver
Amplifier die which operates between 18 and 40 GHz.
The amplifier provides 18.5 dB of gain, +27 dBm
Output IP3, and +22 dBm of output power at 1 dB
gain compression, while requiring 280 mA from a +5V
supply. Ideal as a driver amplifier for microwave radio
applications, or as an LO driver for mixers operating
between 18 and 40 GHz, the HMC635LC4 is capable
of providing up to +23.5 dBm of saturated output power
at 15% PAE. The amplifier’s I/Os are DC blocked and
internally matched to 50 Ohms making it ideal for
integration into Multi-Chip-Modules (MCMs).
