Description
The CMD271P3 is a broadband MMIC low noise
amplifier housed in a leadless 3x3 mm plastic
surface mount QFN package. The CMD271P3 is
ideally suited for EW and communications
systems where small size and low power
consumption are needed. The broadband device
delivers 20 dB of gain with a corresponding
output IP3 of +27 dBm and a noise figure of 1.8
dB at 8 GHz. The CMD271P3 is a 50 ohm
matched design eliminating the need for external
DC blocks and RF port matching.
