Power Dividers

ET Industries announced its newest product line, power dividers to 65 GHz. The model D-1865-2 is a two-way power divider and model D-1865-4 is a four-way power divider that spans the frequency range from 18 to 65 GHz. Amplitude and phase imbalance are ±1.0 dB and ±12° maximum. Isolation is 20 dB minimum. VSWR is less than 2.0:1. The maximum insertion loss is 3.5 dB for the two-way and 6.0 dB for the four-way. Connectors are “V” 1.85 mm females. Eight-way and sixteen-way power dividers to 65 GHz are also available.

Pseudo Elliptic Bandpass Filter

KR Electronics introduces part number 2910, a surface-mount 875 MHz pseudo elliptic bandpass filter. The filter has a typical insertion loss of 3.5 dB and minimum 3 dB bandwidth of 42 MHz. The filter attains over 50 dB rejection by 831 and 920 MHz. The use of elliptic bandpass at bandwidths as low as 5 percent allows superior performance to all-pole designs in a smaller package. The filter is supplied in a surface-mount package measuring 2.0" × 0.5" × 0.3" and can also be supplied connectorized. The filter can be customized for other center frequencies and bandwidths.

77 GHz Economic Sensor

Model SRF-77120910-01 is a low cost 77 GHz sensor designed for Doppler speed measurement. It is constructed with a high performance circular horn antenna, a linear to circular polarizer and T/R diplexer. It also incorporates a balanced mixer and a high performance Gunn oscillator. The sensor features a 12 degree 3 dB beam width, 10 dBm output power and 9 dB conversion loss. The sensor can readily be modified to offer different beam widths, dual channel (I-Q) output or FMCW versions.

Quick-release Waveguide Couplings

Manufactured from Alochromed aluminum with stainless-steel threaded inserts and screws, the QRF series of couplings attach to the rear of waveguide flanges. The self-aligning couplings are equipped with dowels to ensure precise positioning, while the use of spring-loaded screws prevents parts from being lost. The screws are designed to be finger tightened and also incorporate hex bolts to allow the use of a torque wrench. Available in different versions to suit all popular waveguide sizes, the QRF series is designed for rapid installation and is suitable for maintenance personnel in the defense, broadcast and telecommunications sectors.
