Custom MMIC continues to add to its extensive low noise amplifier (LNA) and phase shifter MMIC portfolio with the CMD270P3 LNA and CMD174 phase shifter.
LNA — The CMD270P3 is a 4 to 8 GHz LNA in a leadless 3 mm x 3 mm plastic surface-mount package. The LNA has a noise figure of 1.7 dB and greater than 16 dB gain, with an output 1 dB compression point of +18 dBm. The CMD270P3 is a 50 Ω design, eliminating the need for external matching and DC blocks.
The CMD270P3 is well-suited for EW and communications receivers, where high performance, small size and low power consumption are needed. It can also be used as an alternative to Custom MMIC's CMD185P3, with pin and performance compatibility.
Phase Shifter — The CMD174 is a GaAs MMIC 5-bit phase shifter in die form that operates from 3 to 6 GHz and provides 0 to 360 degrees of monotonic phase coverage, with an LSB of 11.25 degrees. The device, controlled with negative logic of 0 and −3 V, has an insertion loss of 7.6 dB and a phase error of ±2 degrees. The CMD174 is a 50 Ω matched design.
The CMD174 is well-suited suited for phased array radar applications.
