Description :

The RF-6G is a wide-band RF front-end with fast switching synthesizer and low gain flatness over 500 KHz to 6 GHz coverage. Moreover excellent phase noise performance and high-linearity IF output with 20 MHz bandwidth. Two interfaces, the high-speed SPI for 10 Mbps and the asynchronous PH5 control at 115 kbps. On all bands RF6G provides very good tuning characteristics needed for professional signal analysis. Typical applications for the tuner is the integration into high-end monitoring systems, for interference detection and investigation, in field-strength measurements, radio propagation research, close-range detection of illegal eavesdropping devices. This AOR provides high accuracy on 45.05 MHz IF output for external peripherals, factory calibration ensures that the output is correlated to the antenna RF input within only few dB and this on the entire receive range:

The RF 6G has two RF antenna connectors, selectable, and a low noise down converter. A direct digital synthesizer is employed for the 1° local oscillator to ensure fast frequency switching of less than 3 mS. An input filters bank pre-select the RF spectrum:
