MAX7060: Programmable ASK/FSK transmitter provides frequency and output-power flexibility

Additionally, the RF output power is SPI(TM) programmable between +14dBm and -14dBm in 1dBm steps, thus enabling users to maximize transmit power while complying with multiple regulatory requirements. To maintain a good output-power match across a broad range of frequencies, the MAX7060 also contains a programmable matching capacitor that is connected in parallel with the PA output. This combination of integration and flexibility makes the transmitter well suited for power-sensitive applications such as home security systems, remote controls, and garage door openers.

The MAX7060 operates from either a single 2.1V to 3.6V power supply, or internal regulators can be used for supply voltages between 4.5V and 5.5V; it draws 5nA (typ) in shutdown mode. It is fully specified over the -40 degrees Celsius to +125 degrees Celsius temperature range and is available in a 4mm x 4mm, 24-pin TQFN package. Prices start at $2.60 (1000-up, FOB USA).
