EMC Technology, a leader and innovator of high frequency and temperature variable attenuators, introduces the QFA series for passive fixed attenuation from 36 to 50 GHz. Being passive in nature, there is no signal distortion, phase shift or time delay. The attenuator structure is internally tuned for optimum performance beyond Ka-band, with the added benefit of being a truly symmetrical, bidirectional attenuator.

The QFA is available in surface-mount packaging and suitable for pick and place applications. The QFA was developed to address commercialization of point-to-point radio, high frequency transceivers and phased-array radar. The device comes in two styles, microstrip and coplanar, with excellent frequency response from 36 through 50 GHz and is available in designs of 0 to 10 dB in 1 dB increments over the operating temperature of -55° to +125°C. The QFA handles 200 mW of input power and has a very small 1206 footprint. Several values are available in RoHS versions and all can be supplied on tape and reel for high volume pick and place applications.
