Monolithic microwave integrated circuit (MMIC) developer Custom MMIC of Westford, MA, USA has added to its growing line of standard gallium arsenide (GaAs) amplifier products by launching the CMD163, a 17-27GHz low-noise amplifier (LNA) in die form.
Gain is +24dB, noise figure is less than 1.3dB, and P1dB (output at 1dB compression point) is +19dBm across the 17-27GHz bandwidth. Additionally, the CMD163 utilizes an all-positive bias scheme, eliminating the need for negative voltages and expensive sequencing circuitry. Bias conditions are Vdd = 4V @ 120mA and Vgg = 3.0V.
Custom MMIC says that the CMD163 is suited to 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, apart from from bypass capacitors.
The LNA is also available in packaged form as the CMD163C4, with similar performance.
