NuFilter™ 03BPCV-2113-SFSF-M01 S-Band Bandpass Cavity Filter

The NuFilter™ 03BPCV-2113-SFSF-M01 is a 3-pole S-band bandpass cavity filter with a passband of 2108 to 2118 MHz, a 10 MHz bandwidth centered at 2113 MHz. It is designed to reduce harmonics at the output of transmitters operating in S-Band and accepts RF input power up to 50 W CW.

S-Band Bandpass Cavity Filter Performance

The filter provides harmonic filtering and out-of-band rejection of 57 dB typical (41 dB minimum) at 1932 and 2294 MHz. Passband insertion loss is 0.98 dB typical at the 2113 MHz center frequency and 1.238 dB maximum across the passband. Passband flatness is 0.1 dB typical, and VSWR within the passband is 1.5:1 maximum.
