Broadband RF switches

31st May 2016

Posted By Paul Boughton


Integrated Device Technology introduces two high-isolation, low-loss, high linearity broad band RF switches for a wide variety of applications.

Operating at 50 to 8,000MHz, the IDT F2932 and F2933 are silicon-based, low-distortion 50ohm single-pole, double-throw (SPDT) switches. With industry-standard 4x4mm 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 4GHz the F2932 and F2933 deliver:

* High isolation of 66dB

* Low distortion of 64dBm IIP3@15dBm tones, 1MHz channel spacing

* Insertion loss of 0.93dB

* P1dB of >35dBm.

The inherent benefits over most competitive products, particularly when compared to typical GaAs-based switches, are:

* Better RF performance

* Greater reliability

* Easier integration

Lower total solution cost.

F2932 and F2933 offer similar RF performance, pin out and control, with the F2932 having an additional Enable/Disable feature allowing all RF paths to be put into an off state and disabling the VCTL feature.
