Custom MMIC adds LNA and Phase Shifter MMICs


The LNA is a C Band, 4-8 GHz device housed in a leadless 3×3 mm plastic surface mount package. The LNA delivers greater than 16 dB of gain with a corresponding output 1 dB compression point of +18 dBm and a noise figure of 1.7 dB. The LNA is a 50 ohm matched design eliminating the need for external DC blocks and RF port matching.

The LNA, designsted CMD270P3, is suitable 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 CMD185P3, based on pin and performance compatibility.

The CMD174 die is a GaAs MMIC 5-bit phase shifter that operates from 3 to 6 GHz and provides 0 to 360 degrees of monotonic phase coverage, with a LSB of 11.25 degrees. The device is controlled with negative logic of 0 and -3 V and features an insertion loss of 7.6 dB and a phase error of ± 2 degrees. The CMD174 is a 50 ohm matched design.

The CMD174 is  suitable for phased array radar applications
