Monolithic microwave integrated circuit developer Custom MMIC of Westford, MA, USA has added to its low-noise amplifier (LNA) and phase-shifter MMIC portfolio with the CMD270P3 and CMD174.

Housed in a leadless 3mm x 3mm plastic surface-mount package, the CMD270P3 is a C-band, 4-8GHz LNA that delivers greater than 16dB of gain with a corresponding P1dB (output power at 1dB compression point) of +18dBm and a noise figure of 1.7dB. The CMD270P3 is a 50Ω matched design, eliminating the need for external DC blocks and RF port matching.

The CMD270P3 is suitable for electronic warfare (EW) and communications receivers where high performance, small size and low power consumption are needed. It can also be used as an alternative to the CMD185P3, based on pin and performance compatibility.

The CMD174 die is a gallium arsenide (GaAs) MMIC 5-bit phase shifter that operates at 3-6GHz and provides 0-360° of monotonic phase coverage, with a LSB of 11.25°. The device is controlled with negative logic of 0 and -3V and features an insertion loss of 7.6dB and a phase error of ± 2°. The CMD174 is a 50Ω matched design, and is suitable for phased-array radar applications.
