Failsafe SPDT Switch
Guerrilla RF Inc. introduced the GRF6011, the first member of the company’s growing list of failsafe switch and amplifier devices. Failsafe refers to the characteristic whereby one switch path defaults to a low loss state, when all power is removed. A key application for this single-pole, double-throw (SPDT) switch is at the low noise amplifier (LNA) in a tower mounted amplifier (TMA), where this failsafe functionality is typically implemented using expensive mechanical relays or cumbersome Schottky diode switches external to a traditional LNA device.
