When your circuit design requires amplitude compression, Spectrum Microwave delivers the RF limiting function with its line of RF limiting amplifiers. These amplifiers are useful for protecting subsequent components from input overdrive and removing amplitude modulation from FM signals.

      Spectrum Microwave offers receiver protection for frequencies from 5 MHz to 1000 MHz. With input power levels up to +26 dBm, use as a clean-up limiter with higher power limiters or stand-alone for lower power requirements. The limiting levels can be adjusted by varying the bias voltage
