Our circulators and isolators are available with connectors or as surface-mount types. Power handling ranges from 2 to 300 W averages and 500 W peaks for circulators and 2 W for isolators.

Anatech’s standard LC duplexers combine insertion loss of 1 dB or less with isolation greater than 50 dB, return loss greater than 15 dB, and power handling ability up to 20 W.  Anatech LC duplexers are manufactured using inductors and capacitors with a high Q factor, which provides low insertion loss and high selectivity.

Our cavity bandpass filters for 700 MHz LTE are available for all uplink and downlink bands and meet the stringent requirements posed by dense channel spacing. They have more than 40 dB of rejection at 700 kHz from passband to stopband at band edges, low insertion loss, and PIM as low as -150 dBc.

The AM1485DC854 30-dB dual-directional coupler operates from 800 to 2170 MHz, handles 500 W average and 3 kW peak RF power input, and is well suited for base station RF power monitoring. It has very low third-order intermodulation distortion of -155 dBc, insertion loss of 0.5 dB, coupling flatness of 0.75 dB, directivity of at least 25 dB, and VSWR of 1.07:1.

The AM5725B1162ceramic bandpass filter has a center frequency of 5725 MHz, a 1-dB bandwidth of 90 MHz (5680 to 5770 MHz), insertion loss of 5 dB or less, passband ripple of 1.2 dB or less, return loss of at least 12 dB, and rejection of at least 30 dB at 5525 MHz and 5925 MHz.

The AB907B781 cavity bandpass filter is designed for outdoor applications and has a center frequency of 907.5 MHz, 1.5-dB bandwidth of 905 to 910 MHz, insertion loss of 3 dB or less, and out-of-band rejection of at least 75 dB from 850 to 889 MHz and 919 to 950 MHz.

The Wifi4S2440-7 cavity bandpass filter has a center frequency of 2440 MHz and is designed for indoor or outdoor use in Wi-Fi hot spots. It has a bandwidth of 2425 to 2455 MHz, insertion loss of less than 2 dB, ripple of less than 2 dB, and return loss greater than 15 dB.

The AB913B488 water-resistant cavity bandpass filter has a center frequency of 913 MHz, bandwidth of 20 MHz, insertion loss of 1.6 dB, rejection of at least 40 dB at 895 MHz and 931 MHz, and handles 30 W.

The AE800L8686 low-pass filter has a pass-band of DC to 800 MHz with insertion loss of less than 4 dB, ripple of 0.1 dB or less, and rejection at 1000 MHz of at least 40 dB. The filter measures 4 x 1.25 x 0.75 in. and has BNC female connectors.

The AM1650DC837 is an 8-dB directional coupler that operates from 800 to 2500 MHz with 20 dB directivity, insertion loss of less than 1.1 dB, isolation of 28 dB, and IMD of -140 dBc. VSWR is 1.2:1 or less and power handling ability is 40 W.
