ADF7901 - High Performance ISM Band OOK/FSK Transmitter

Datasheet Summary

Description

The ADF7901 is a low power OOK/FSK UHF transmitter designed for use in RF remote control devices.

It is capable of frequency shift keying (FSK) modulation on eight different channels, selectable by three external control lines.

OOK modulation is performed by modulating the PA control line.

Features

  • Single-chip, low power UHF transmitter 369.5 MHz to 395.9 MHz frequency operation using fractional-N PLL and fully integrated VCO 3.0 V supply voltage Data rates up to 50 kbps supported Low current consumption 26 mA at 12 dBm output at 384 MHz Power-down mode (.

It is capable of frequency shift keying (FSK) modulation on eight different channels, selectable by three external control lines. OOK modulation is performed by modulating the PA control line. The on-chip VCO operates at 2× the output frequency. The division by 2 at the output of the VCO reduces the amount of PA feedthrough.
