CMD228P4

2-6 GHz (S, C Band) Low Noise Amplifier MMIC

Qorvo's CMD228P4 is a broadband GaAs MMIC low noise amplifier housed in a leadless 4x4 mm plastic surface mount (SMT) package. The CMD228P4 is ideally suited for microwave radios and S and C band applications where high gain, low noise figure and low power consumption are critical design requirements. The broadband device delivers 28 dB of gain with a corresponding output 1 dB compression point of +13 dBm and a noise figure of 1.5 dB. The CMD228P4 low noise amplifier MMIC is a 50 ohm matched design eliminating the need for external DC blocks and RF port matching.
