rfRXD0420 DESCRIPTION
The rfRXD0420 is a stand-alone receiver module that can be used in a variety of ways.
• It can be plugged into the PICkit 1 FLASH Starter Kit expansion header J3 for
• The receiver module can be installed in any project for proof-of-concept, demonstration, or
A detailed description of the rfRXD0420 UHF ASK/FSK/FM receiver is provided in the
data sheet, DS70090.
A detailed description of the rfRXD0420 receiver module design is provided in application
note, AN860.
FIGURE 3-1:
Table 3-2 lists the pinout for the rfRXD0420 receiver Module.
TABLE 3-2:
The antenna connection is a 0.055 inch pin receptical. A simple small diameter wire
(AWG 24) antenna can be constructed and inserted into the receptical. The length of
the antenna wire depends on the frequency.
where
The length of the antenna wire in inches can be found for a given frequency using the
following formula:
Alternatively, the pin receptical can be removed and an alternate antenna connection
can be made. For example, a coaxial wire can be connected to the antenna pad on the
front side of the PCB and ground pad on the back side of the PCB.
