Anatech Intros Directional Coupler, Bandpass Filter, Isolator, Duplexer


Anatech Electronics has released new designs for a 902 to 928 MHz Cavity Bandpass Filter, an 1850 to 1910 MHz / 1930 to 1990 MHz Cavity Duplexer, a 840 to 960 MHz Circulator , and a 5 to 18 GHz 8-Way Power Divider. All can be ordered directly through our AMCrf web store.

Cavity Bandpass Filter902 to 928 MHz Cavity Bandpass Filter

The AB915B939 cavity bandpass filter has a center frequency of 915 MHz and a 26 MHz passband between 902 and 928 MHz. The filter’s insertion loss is 1.5 dB or less, and power handling ability is 5 W. Out-of-band rejection is 45 dB between 850 and 894 MHz and 90 dB between 944 and 952 MHz. It measures 7 x 2.45 x 3 in. and uses Type-N connectors.
1850 to 1910 MHz/1930 to 1990 MHz Cavity Duplexer

The AD1880-1960D274 cavity duplexer has a first passband of 1850 to 1910 MHz and second passband of 1930 to 1990 MHz with less than 0.6 dB of insertion loss and isolation of at least 40 dB. Passband ripple is 0.5 dB, return loss is greater than 15 dB, and operating temperature range is -40° C to +85° C. The duplexer measures 7.10 x 3.25 x 2.40 in. and uses SMA female connectors.
840 to 960 MHz Circulator

The AM840-960CIR1112 circulator operates from 840 to 960 MHz with isolation of at least 20 dB, insertion loss of 0.4 dB, VSWR of 1.25:1, and power handling of 65 W average and 500 W peak. The circulator will operate over a temperature range of 0° C to +50° C, measures 35 x 40 x 26 mm, and uses SMA female connectors.
8-Way Power Divider5 to 18 GHz, 8-Way Power Divider

The AM11500PD1335 eight-way power divider operates from 5 to 18 GHz with insertion loss of less than 1.5 dB, VSWR of 1.7:1, amplitude balance of 0.5 dB, phase balance of 12 deg., and isolation of at least 15 dB. It will handle 30 W CW, measures 4 x 2 x 0.4 in. and uses SMA female connectors.
