Custom MMIC introduces 5-9GHz Low Noise GaN Amplifier

Custom MMIC has announced the release of the CMD218, a 5-9 GHz low noise amplifier (LNA) in die form, to its growing line of standard GaN products.

The CMD218 offers a gain of 22 dB, output of 1 dB, compression point of +19.5 dBm, and noise figure of less than 1.25 dB across the 5 to 9GHz frequency range. In addition, without an input limiter, the CMD218 can survive high incident power levels up to 5 W with no degradation in performance.

The CMD218 is a 50Ω matched design, eliminating the need for external DC blocks and RF port matching. In terms of biasing, the CMD218 can operate from a supply voltage of 5 V to 28 V, and typically draws 100 mA of quiescent current. A negative gate voltage is required for proper operation.

The LNA is suited for microwave radios and C- and X-band applications where small size and low power consumption are needed. Applications include point-to-point and point-to-multipoint radios, military and space, and test instrumentation.
