-SYSCLK (13) "TCXO ref out"
|
|
|
|
|
|
VCTRL on TCXO is open on actual part (so don't need R4,5 , C9, JP5)
|
|
|
|
Have plenty of following part - (1.8V LDO)
|
|
- (TCXO)
|
|
|
|
Test Goal: Send and receive a test pattern. could use one to transmit and one to receive. Bit error rate test.
|
|
Figure out how to test radio circuit blocks in succession. (Mini 50 ohm flex lines and terminations?)
|
|
Ask if andrew wants full TX/RX on both radios.
|
|
|
|
In the future need LDO's separate for UHF and L band LNAs @ 2.7V.
|
|
|
|
On transmit UHF PA will raise radio power to 2.5 W. May need 0.350 A for radios alone.
