The DK-2 from Spacek Labs in an RF Detector that operates from 18 to 26.5 GHz. It has a sensitivity of 3000 mV/mW at -20 dBm input power and flatness of ±2 dB across the band with a typical tangential sensitivity of -45 dBm in a 1 MHz video bandwidth. This detector is a very cost-effective way of measuring power in the K-band spectrum. It can handle up to 18 dBm of input power and can be used as a fast data rate receiver, with up to 3 GHz bandwidth at the 3 dB point into a 50-ohm load. The detector is available in an extremely rugged and compact module that measures 1.6 x 0.9 x 0.3 inches with WR-42 (UG595/U) input and SMA-female output connector.
