The loop filter acts as a very large capacitor and resistor to introduce a long R-C time for smoothing. It uses a small capacitor and the very high input impedance of an op amp buffer. During the TX_EN (Whitecap IC Pin C1) period when the transmitter is preparing to operate, the capacitor charges. On receipt of DM_CS (Whitecap IC Pin E2), when the Transmitter actua ...
