A new directional coupler that operates in the frequency range of 0.5 to 8.0 GHz offers nominal coupling of 30 dB in a compact package. Model 158030 is uniquely designed for systems applications where external leveling, precise monitoring, signal mixing, or swept transmission and reflection measurements are required. The directional coupler also lends itself to wireless designs and many test and measurement applications from UHF through C-band, including electronic warfare (EW), commercial wireless, SATCOM, radar, signal monitoring and measurement, antenna beam forming, and EMC testing environments. Its compact size makes it ideal for many space-restricted applications. The unit comes with industry-standard SMA female connectors, with optional SMA male and N female connectors available. The compact package measures just 5.25 x 0.53 x 0.72” and weighs only 3.8 ounces. Operating temperature is -54 to +85°C.
