through Figure 23 are PCB pictures. The QR21 9BPF
is a good starting po int for the prototyping of most
applications. Current design offers two an tenna
options: A wire antenna or 50 Ω SMA ante nna. The
SMA connection also allows an RF sig nal to be
injected for test o r verification. To use an antenna

such a s a 50 Ω whip, remove the SMA and solder the
whip antenna in the hole on the PCB instead. A wire
of 22AWG with 167mm (6.-inch) can be used as a
substitu tion if low cost antenna is needed.
Front-End Band Pass Filter
Components L1 and C8 form the band-pass filter at
front of the receiver. Its purpose is to attenuate
undesired outside band noise that degrades the
receiver performance. It is calculated by the parallel
resonance equation:
f = 1/(2×PI×(SQRT L1×C8))
Table 2. Front Band-Pass Filter values for Various
Frequencies
This band-pass filter can be removed if the outside
band noise does not cause a problem. The MICRF219
has built-in image reject mixers which improve the
selectivity significantly and reject outside band noise.
