Two new low noise amplifiers from Custom MMIC, the CMD167 and the CMD167P3, are ideally suited for electronic warfare and communications systems where small die size and low power consumption are needed. The CMD167 is a highly efficient, ultra low noise GaAs MMIC amplifier that operates from 10 to 17 GHz. The CMD167P3 is a packaged version of the amplifier which operates from 8 to 16 GHz. At 14 GHz, both devices deliver greater than 15 dB of gain, with an output 1 dB compression point of +11 dBm and a noise figure of 1.8 dB. Each requiring just a single positive supply voltage for operations, both devices are 50 Ω matched designs, eliminating the need for external dc blocks and RF port matching. The CMD167 MMIC amplifier is available as a bare die for hybrid assemblies, and the CMD167P3 MMIC amplifier is housed in a leadless 3 x 3 mm plastic surface mount package.
