Description
Models BDC-K-26.5-18..26.5GHz & BDC-K-40 - 26.5..40GHz are down-converters available in 18-26.5GHz and 26.5-40GHz frequency range for use with a 2-20GHz tuned receiver. It has a LO input @ 14.5GHz. The RF input connection is a K type connector and the IF output is a SMA type connector.
Model BDC-K-40 - 18..40GHz is an 18-40GHz down-converter for use with a 2-20GHz tuned receiver. The RF input connections are K type connectors and the IF output is a SMA type connector. The down-converter can operate in two bands, 18-26.5GHz (LO = 29GHz) and 26.5-40GHz (LO = 43.5GHz), with the IF output in the range 2.5-17.5GHz to make it compatible with existing communications equipment. It is designed to be compact size, with low noise figure and spurious, and has a built-in local oscillator. The local oscillator consists of a Dielectric Resonator Oscillator (DRO) which is phase locked to an internal reference. The internal reference may in turn be locked to an external 10 MHz reference.
