Ultra low noise MMIC amplifier covers 17 to 27 GHz
The CMD163 has a gain of +24 dB, a noise figure of less than 1.3 dB, and an output 1 dB compression point of +19 dBm across the 17 to 27 GHz bandwidth. Additionally, the CMD163 utilizes an all-positive bias scheme, thereby eliminating the need for negative voltages and expensive sequencing circuitry. Bias conditions are Vdd = 4 V at 120 mA and Vgg = 3.0 V.
The CMD163 is ideally suited for military and space applications, as well as point-to-point and point-to-multipoint communication systems where small die size and high linearity are needed. The LNA is an internally matched 50 ohm design that does not require any external components, aside from bypass capacitors. Additionally, the LNA is available in packaged form as the CMD163C4 with similar performance.
