Given current and future customer expectations to have their devices more connected to everything happening in the world, RF communication is propagating rapidly. In scenarios with longer distances or more crowded RF landscapes, a more powerful RF signal might be required. In this article, find out how the CN0417 RF Power Amp from Analog Devices provides up to 20dB of RF gain.
The CN0417 circuit is built from 3 component modules:
- • ADL5606 1800MHz-2700MHz, 1W RF driver amplifier
- • LTM8045 µModule® DC-to-DC converter with up to 700 mA output current
- • ADT6402 low cost, 2.7V to 5.5V pin-selectable temperature switch
As configured, this circuit provides 20dB of gain, increasing the range for communications protocols such as ISM, MC-GSM, W-CDMA, TD-SCDMA, and LTE. It requires a 5V USB power supply to operate and includes an overtemperature management circuit to ensure the board remains within operational range.
