Custom MMIC Introduces New 4-8 GHz GaN Low-Noise Amplifier
Custom MMIC, a developer of monolithic microwave integrated circuits (MMICs), has announced the release of the CMD219, a 4-8 GHz low noise amplifier (LNA) in die form, to its growing line of standard GaN amplifier products.
The CMD219 has a gain of 23dB, an output of 1dB compression point of +18dBm, and a noise figure of 1.1dB across its operating bandwidth. Typical bias conditions are Vdd = 10 V @ 100mA and Vgg = -2.3 V, although Vdd can vary from 5V to 28V. The CMD219 can also survive input power levels of up to 5W without front-end a limiter.
Ideal applications for the CMD219 include point-to-point and point-to-multipoint radios, military and space, and test instrumentation. All ports are matched to 50Ohm and do not require any off-chip components, aside from the bias networks which require external bypass capacitors.
