The HMI AND HMC series broadband ferrite junction isolators and circulators are available from 18 to 120 GHz. They utilize a low loss H-plane structure in a modified Y-junction format to provide minimum loss with maximum isolation and bandwidth. 2 GHz bandwidths with 20 dB of isolation are standard. Wider bandwidth, high power handling and magnetic shielding are available in select units.

The  AM1650DC834 directional coupler operates over a frequency range of 800 to 2500 MHz with 15 dB of coupling (+/-1 dB), 20 dB of directivity, 0.4 dB insertion loss, at least 35 dB of isolation, and intermodulation distortion of -140 dBc. It has a VSWR of 1.2:1 and handles 40 W CW. The coupler operates over a temperature range of -30^o to +60^o C, has Type-N connectors, and measures 4.2 x 1.4 x 0.9 in.

The AS36CN803 crystal notch filter has a center frequency of 36 MHz, low-side passband of -80 to -2 kHz, high-side passband of 2 to 80 kHz, insertion loss of 4 dB, ripple of 1 dB or less, and has a maximum input power of 10 dBm. The filter uses SMA female connectors.

Anatech’s AM836-881D177 ceramic duplexer has a Band 1 passband of 824 to 849 MHz, a Band 2 passband of 869 to 894 MHz, and insertion loss in either band of less than 3.3 dB. Return loss is greater than 13 dB, isolation is greater than 43 dB in Band 1 and greater than 60 dB in Band 2, and rejection ranges between 43 dB and 50 dB.

The AE600H9800 highpass filter has a cutoff frequency of 600 MHz and a passband of 2 to 10 GHz. Insertion loss at its center frequency is less than 2 dB, return loss is greater than 10 dB, rejection is at least 30 dB from DC to 932 MHz, and it is housed in a package measuring 1 x 0.7 5 x 0.243 in. The filter uses Type-N female connectors.

PMI Model No. TD-2G18G-RL-CD-SFF is a high speed threshold detector designed to operate over the 2.0 to 18.0 GHz frequency range with an adjustable threshold level of -30 to -10 dBm and a VSWR of 3.0:1 max.  This unit is supplied with field removable SMA Female connectors in a small package measuring 1.1" x 0.6" X 0.19".

PMI Model No. DTA-14G40G-32-CD-2 is a 10 Bit programmable attenuator with step resolution as low as 0.04 dB which provides over 32 dB of attenuation over the frequency range of 14.0 to 40.0 GHz.  This model is offered in a slim line housing measuring 2.0" x 1.8" x 0.5" with 2.92 mm female connectors and operates on a single +15 VDC supply with only 40 mA of current consumption typically.

Renaissance has designed a high power drop-in isolator for IFF transceiver application. Covering 1020 to 1040 MHz, this isolator has just 0.40 dB of insertion loss over -30 to +70 C while handling 100 W forward and reverse power levels.

Power, efficiency, and bandwidth. Werlatone provides all three qualities in its growing line of high power 2-way combiners/dividers. Model D9392 is no exception. Covering the full 500 to 2500 MHz, the D9392 is conservatively rated at 500 W CW, and operates with less than 0.3 dB of insertion loss.

Our newest addition to our 20 to 1000 MHz family of products is the Model D9317. This 200 W CW, 2-way combiner operates with less than 0.7 dB insertion loss, and a minimum of 15 dB isolation. Measuring just 3.75 x 3.75 x 0.9", the D9317 is ideal for combining four 50 W modules.
