Abstract
A radio-frequency (RF) amplifier device comprises a signal input for receiving an RF electrical signal, a variable-gain amplifier for amplifying the received signal, and a signal output for outputting the amplified signal. The device has a binary input for switching a gain of the amplifier between a first level and the custom gain level. Configuration logic receives serialised data encoding a custom gain level at a serial input, and stores data representative of the custom gain level in a memory of the device. Gain-control logic reads the data representative of the custom gain level from the memory, and sets the gain of the amplifier to the first level or to the custom gain level in dependence on a state of the binary input.
