The CMX017 is a single chip UHF FM/FSK transmitter that combines both the RF VCO Modulator and RF
Power Amplifier. It is suitable for both audio FM and digital FSK transmissions.
A buffered oscillator output provides the RF signal drive to an external synthesizer or fixed frequency phase-
locked loop for channel frequency selection. Modulator output power is adjustable over a 20dB range and the
integrated power amplifier delivers up to +20dBm. The device also includes a powersave mode: “Transmit
Standby” and a zero-power mode: “Sleep”. These allow independent power down control of both the
modulator and power amplifier, thereby maximizing battery life. The device can be used in conjunction with
the CMX018, a double-conversion super-heterodyne receiver, to implement a complete UHF radio link.
The CMX017 operates from a 2.7V to 3.3V power supply and is available in the following package style:
28-pin SSOP (CMX017D6).
