Hot-selling and scarce ADF7025BCPZ High Performance ISM Band Transceiver IC QFN spot stock

Product Descriptions

The ADF7025 is a low power, highly integrated FSK transceiver.It is designed for operation in the license–free ISM bands of433 MHz, 863 MHz to 870 MHz, and 902 MHz to 928 MHz .The ADF7025 can be used for applications operating under theEuropean ETSI EN300-220 or the North American FCC (Part 15)regulatory standards . The ADF7025 is intended for wideband,high data rate applications with deviation frequencies from100 kHz to 750 kHz and data rates from 9.6 kbps to 384 kbps .A complete transceiver can be built using a small number ofexternal discrete components, making the ADF7025 verysuitable for price-sensitive and area-sensitive applications .

The transmit section contains a VCO and low noiseFractional-N PLL with output resolution of <1 ppm . The VCOoperates at twice the fundamental frequency to reduce spuriousemissions and frequency pulling problems .

The transmitter output power is programmable in 0.3 dB stepsfrom −16 dBm to +13 dBm.The transceiver RF frequency,channelspacing,and modulation are programmable using a simple 3-wireinterface.The device operates with a power supply range of 2.3 Vto 3.6 V and can be powered down when not in use .
