Overview
The ADF7020-1BCPZ is a low power, highly integrated FSK/GFSK/ASK/OOK/GOOK transceiver IC designed by Analog Devices Inc. for operation in the low UHF and VHF bands. This device is highly versatile, allowing users to set the operating frequency anywhere between 135 MHz and 650 MHz, and as low as 80 MHz using a divide-by-2 circuit. It features a low noise fractional-N PLL with an output resolution of less than 1 ppm, making it suitable for frequency-hopping spread spectrum (FHSS) systems. The transceiver is particularly suited for price-sensitive and area-sensitive applications due to its minimal requirement for external discrete components.
