Werlatone introduces its new line of high power, absorptive filters with the Model AF9350. This UHF, low pass filter covers the 10 to 500 MHz band, and has an average power rating of 400 W CW. The AF9350 incurs a rejection of 45 dB minimum at the 750 to 3000 MHz band, and power rating of 25 W CW from 501 to 5000 MHz.

The Model AF9349 is a VHF, low pass absorptive filter, covering the 10-150 MHz bandwidth. This high power design is conservatively rated at 500 W CW (Pass Band), and 100 W CW (Stop Band). The Rejection is guaranteed at -50 dB from 300 to 1500 MHz.

Mini-Circuits has teamed with Modelithics Inc. to develop high-accuracy simulation models of Mini-Circuits’ 3.2 x 1.6 mm case-size surface-mount LFCN low-pass filters and HFCN high-pass filters. The substrate-scalable models are validated up to 13 GHz, depending on the frequency band specifications of each filter.

Werlatone offers the Model C9688, a 40 dB dual directional coupler, covering the full 1 to 1000 MHz band. Rated at 800 W CW, the C9688 will operate into 3:1 Load VSWR, and is ideal for applications spanning multiple frequencies.

Mercury Systems' control components capabilities include custom control devices and multi-function assemblies; purposely built to suit your application needs. These may combine active and passive circuit elements, such as switch filters, switched attenuators, phase shift switches or complete front-ends.

Renaissance has released a new L-Band 4.5 kW peak power drop-in circulator operating from 1 to 1.12 GHz. With insertion loss of less than 0.2 dB and with return loss and isolation over 23 dB, the circulator is ideal to duplex an antenna with HPA and a receiver. This circulator has been customized to withstand 50 W of forward and 100 W of reverse power at the same instance without arcing or corona failures.

Renaissance has developed a new low cost, high power, drop-in isolator to protect expensive amplifiers from unwanted reflected power levels at S band frequencies. Covering 2.7 to 2.9 GHz, this isolator provides a VSWR of 1.25:1 at input and output ports with loss of 0.4 dB and isolation of 20 dB over -30 to +85 C.

The AE70NS2067 notch filter has a notch bandwidth of 68 MHz to 72 MHz, rejection of at least 30 dB, a low-side passband of DC to 64 MHz and high-side passband 76 to 150 MHz. Insertion loss is less than 1 dB, and the filter measures 4 x 1.25 x 0.75 in. and uses SMA female connectors.

The AM1500PD902 two-way power divider cover 800 to 2200 MHz with insertion loss of 0.5 dB, isolation of at least 18 dB, amplitude balance 0.5 dB, phase balance of 5 deg., and VSWR of 1.4:1. It will handle 100 W CW, uses Type-N female connectors, and measures 2.1 x 2.1 x 1 in.

Vaunix family of LDA series digital attenuators offer attenuators with up to 120 dB of programmable attenuation through 6000 MHz. The LDA-102E and LDA-602E both have input power handling of up to 2 W. The LDA digital attenuators can also be used in WiMAX, 3G, 4G, LTE, DVB Fading Simulators, and engineering and production test labs.
