| RF ASK Modules at
315, 418 & 433.92Mhz !  Low Cost Solution for Telemetry and
Radio Control.
We have mini size transmitter TWS434 and receiver
RWS434 at various frequencies.
The transmitter speed is up to 3Kbps ( uses SAW
device ) and the receiver is 5Kbps ( LC
super-regen. ).
The operation range is up to 200 feet ( 70 mts ).

RWS434A SAW Based Receiver
---------------------------------------------------------------------------------------------
These modules operate on 433.92, 418 or 315 Mhz., same as
the standard RWS 434 & TWS 434 modules but they have made
significant changes in the size of the unit. They are SAW
based and offer about 100 meters range in Line-of-Sight
operating form 2-12 volts. The new version has a data rate of
4.8KB/s, over double the speed of the previous version and
still provides 16DBm of output power off under 20mA of
current. The module uses ASK as the form of modulation and has
both digital and analogue outputs.
The size and simplicity of these units make them a
professional and economical solution for many wireless
applications. Is full compatible with the older version of the
RWS433 for the advantage of people with existing units however
we would recommend their use with the New RWS433A. Freq
is 433.92 MHz
The unit price is only US$4.70 e.a. for
1000 pieces.
