The MP1809 is a crystal-controlled single channel miniature VHF transceiver featuring the very latest in RF design techniques and components. Specifically designed and optimised for the reception of audio bandwidth data, it is used in OEM equipment to provide a half-duplex wireless data link.
A CMOS compatible interface allows control of transmitter and receiver functions combining simplicity of use with high performance.
The receiver utilises low power consumption circuitry throughout to minimise current drain. Fast turn-on and off times allow power strobing to further enhance power drain.
The receiver performance, being the major factor in achieving good radio ranges, has been optimised by use of high quality miniature helical filters and high specification crystal filters.
Orders should specify in which country the units are to be used.
This model is also available in transmitter-only and receiver-only versions.
A range of modem boards is available to allow RS232 data streams to be sent.
