Typical Applications
This HMC504LC4B is ideal for:
• Point-to-Point Radios
• Point-to-Multi-Point Radios
• Military & Space
• Test Instrumentation
The HMC504LC4B is a GaAs MMIC Low Noise
Wideband Amplier housed in a leadless 4x4 mm cer-
amic surface mount package. The amplier operates
between 14 and 27 GHz, providing up to 19 dB of
small signal gain, 2.2 dB noise gure, 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 cap-
acity microwave radios or VSAT applications. This
versatile LNA is also available in die form as the HMC-
ALH476.
