¤· LNB (low-noise block) converter in a satellite TV receiver: RF = 10.7-11.8GHz, IF = 0.95-1.95GHz

A low-noise block converter with the lid and horn removed exposing the complex circuitry inside, with the exception of the local oscillator which remains covered. The horizontal and vertical polarisation probes can be seen protruding into the circular space where the horn is normally attached. Two output connectors can be seen at the bottom of the device.
