Broadband RF Switch Maintains Low Insertion Loss

25 May 2016

Integrated Device Technology, Inc. has introduced two high-isolation, low-loss, high linearity broadband RF switches for an F2932 and F2933. They are silicon-based, low-distortion 50-ohm single-pole, double-throw (SPDT) switches. With industry-standard 4 x 4 mm 16-pin QFN packages and drop-in compatible footprints and control, their rich combination of specs make the devices ideal for communications and public safety systems, radar and general purpose switching.

At 4 GHz the F2932 and F2933 deliver isolation of 66 dB, low distortion of 64 dBm IIP3 @ 15 dBm tones, 1 MHz channel spacing, and insertion loss of 0.93 dB.

The F2932 and F2933 offer similar RF performance, pin out and control. The F2932 has an additional enable/disable feature, allowing all RF paths to be put into an off state and disabling the VCTL feature.
