New Japan Radio outdoor amplifiers are the most common in the world. The new models are reliable, inexpensive, lightweight and easy to operate.
The Block Up Converter (BUC) required a 24VDC power, 10 MHz reference and the L-Band signal. All of these needs are supplied by the IF cable connected to an L-Band modem. When we test these BUCs prior to shipping we use a Comtech EFData CDM-570L modem for testing.
With all low power BUCs the published output of 4 watts, is what the manufacturers describe as typical, all of these BUCs tested so far have exceeded the manufacturer's 4W estimate.
