The ADMV4630 from Analog Devices is an Upconverter that converts input frequencies from 3 – 5 GHz to output frequencies from 14 – 14.5 GHz. It internally generates the LO signal from 8.7 to 10.7 GHz via the on-chip Integer N (INT) synthesizer. This upconverter includes filtering to attenuate both the LO feedthrough and unwanted lower sideband. It provides a conversion gain of 19 dB, a sideband rejection of 95 dBc, and a maximum noise floor density of -140 dBm/Hz. This upconverter includes an on-chip power detector and ADC and includes a transmitter synthesizer lock detection.
The ADMV4630 features a digital serial peripheral interface (SPI) that allows fast frequency and gain programming. This SPI interface also allows powering down all circuits and placing the receiver in standby mode to reduce power consumption. It is available in a 40-lead LFCSP package that measures 6 x 6 mm and is ideally designed for various satellite communication (SATCOM) user terminal applications.
