''U4 - (Marked Z252)''
===RF Transmitter Circuit===
The transmitter RF path contains a filter IC, pi matching network, broadband amplifier, and a few more output filter stages.

====Low Pass Filters====
Lowpass Filters are included on the output from the PA and CC1050 to filter out spurs and harmonics from the signal. These are required to meet FCC and [https://www.ntia.doc.gov/ NTIA] emissions requirements.
