L-Band Bandpass Cavity Filter – NuFilter™ 06BPCV-1437.5-SFSF-M01

The NuFilter™ 06BPCV-1437.5-SFSF-M01 is a 6-pole L-band bandpass cavity filter with a passband of 1433.5 to 1441.5 MHz, an 8 MHz bandwidth centered at 1437.5 MHz. It is designed to reduce harmonics at the output of transmitters operating in L-Band and accepts RF input power up to 50 W CW.

L-Band Bandpass Cavity Filter Performance

The filter provides harmonic filtering and out-of-band rejection of 90 dB typical (80 dB minimum) at 1415 and 1460 MHz. Passband insertion loss is 2.4 dB typical at the 1437.5 MHz center frequency and 5.4 dB maximum across the passband. Passband flatness is 1.5 dB typical, and VSWR within the passband is 1.5:1 maximum.
