RF
transmitter and receiver modules
View
These RF Products are ideal for
short-range wireless remote control applications where cost is a primary
concern. These modules require no external RF components except for
the antenna. They generate virtually no emissions, making FCC and
ETSI approvals easy.

Mechanical Dimensions and Pin Description
The
receiver WZ-R434 and WZ-R418 has a sensitivity of 3uV. Operating
voltage is from 4.5 to 5.5 volts-DC, and has both linear and digital
outputs. For
maximum range, we recommend antenna length to be 1/4 wave of the
frequency, That means, for 433.92Mhz, the antenna length is
approximately 17cm long . The typical sensitivity is -103dbm and the
typical current consumption is 3.5mA for 5V operation voltage.

WZ-433AS series RF transmitter modules offer a cost effective,
high-performance solution for remote control type applications.
The transmitters are very small (.25" x .4"), have a wide
operating voltage range (2-12V), and can deliver 0dBm output
power into a 50 ohm load at 3V. SAW-stabilized design guarantees
that the center frequency is accurate to ±40kHz (@3V), making it
suitable for use with any ASK/OOK receiver available.
Low Cost
RCT-433 Super-Regen ASK/OOK Remote Control
Receiver
The WZ-433RP series RF receiver modules offer an extremely low
cost solution for remote control type applications. The
receivers are compatible with almost any ASK or OOK data
transmitter and can receive legally transmitted signals from
distances as far away as 300 feet. The receivers operate at 5V
and draw only 4.5mA.
