Maxim has managed to shrink its new low-power radio transmitter down to 3 x 3 mm square, calling its new MAX1479 the world's smallest VHF/UHF PLL-based ASK/FSK transmitter to deliver more than +10dBm output. In a 16-pin thin QFN package this transmitter is targeted at low-cost, high-volume applications where space is critical, such as tyre pressure monitoring systems, keyfobs, security products, garage door openers, and remote sensors operating in the 300 to 450 MHz band. The device has a simple data interface and a divider-programmable clock-out feature that eliminates the need for an MCU resonator. It is designed to run directly off a lithium cell, down to 2,1 V, consuming only 0,2 nA in standby. Output power is adjustable from -10 dBm to +10 dBm into a 50 Ω load using an external resistor. At the +10dBm power level, it consumes 6,7 mA of current at 315 MHz and 4,5 mA at 0 dBm output. It can transmit at data rates (Manchester encoded) up to 100 Kbps in ASK and 20 Kbps in FSK.
