VHF/UHF transmitter for ASK data transmission

25 June 2008 Telecoms, Datacoms, Wireless, IoT

The new MAX7058 from Maxim is a crystal-referenced, phased-locked loop (PLL) VHF/UHF transmitter for transmitting OOK/ASK/FSK data at 315 MHz or 390 MHz. It supports switched operation with a single 15 MHz crystal, and can operate at any two frequencies in the 300 MHz to 450 MHz range with the use of different crystal frequencies. To enable this flexibility, it integrates a wideband VCO with internal tuning capacitors that can be programmed for matching the impedance of the power amplifier (PA) to the antenna. This topology ensures highly efficient transmission at multiple operating frequencies, thus making the device ideal for power-sensitive applications such as home security systems, remote controls and garage door openers. The MAX5078 operates from a single 2,1 V to 3,6 V supply, and draws less than 1 microamp in standby mode and less than 8 mA in transmit mode (50% duty cycle OOK).
