General Description
The HMC504LC4B is a GaAs MMIC Low Noise
Wideband Amplifier housed in a leadless 4x4 mm cer-
amic surface mount package. The amplifier operates
between 14 and 27 GHz, providing up to 19 dB of
small signal gain, 2.2 dB noise figure, and output IP3
of +26 dBm, while requiring only 90 mA from a +4V
supply. The P1dB output power of up to +17 dBm
enables the LNA to function as a LO driver for balan-
ced, I/Q or image reject mixers. The HMC504LC4B
also features I/Os that are DC blocked and internally
matched to 50 Ohms, making it ideal for high capacity
microwave radios or VSAT applications. This versatile
LNA is also available in die form as the HMC-ALH476.
