Amp Minimizes Noise To 6 GHz

July 8, 2010

Model PMA-545+ is a low-noise monolithic-microwave-integrated-circuit (MMIC) amplifier from Mini-Circuits with outstanding noise figure of typically 0.8 dB across an extremely wide bandwidth of 0.05 to 6.00 GHz. Internally matched to 50 Ohms, the low-noise amplifier (LNA) offers typical gain of 20 dB and typical output power of +20 dBm at 1-dB compression. It delivers a high third-order intercept point of +36 dBm at 1 GHz. The MMIC amplifier is supplied in a compact surface-mount package and draws typically 80 mA current from a single +3-VDC supply.
