The TriQuint TGL2201-SM is a packaged dual stage GaAs VPIN limiter that operates over the 2 to 12 GHz band. Vertical PIN diodes provide the limiting action at high input signal levels and low loss at small signals.

The TGL2201-SM is suitable for a variety of wideband systems such as low noise amplifier (LNA) / receiver protection in radars, phased arrays and jammers.

The part is lead-free and RoHS compliant.
