General Notes:
1. The PMP-3R series of high frequency, voltage controlled phase modulators
covers 10 to 500 MHz. Phase modulation is achieved by the application of a DC
coupled signal between 0 and 15 volts and can have a rate up to 10% of the RF
center frequency when driven from a low impedance source.
2. The modulating signal varies the capacitance of two varactor diodes which form
part of a tuned LC circuit connected across the output ports of a 90° Quadrature
Hybrid. The resulting reactance changes cause a shift in the insertion phase of an
RF signal passed through the hybrid. A single unit provides more than 180° of
phase shift, peak-to-peak.
3. The PMP-3R series of voltage variable phase modulators are designed for
analog modulation of an RF carrier. For digital modulation, the JPP and BPP series
of quadrature and bi-phase modulators are suggested.
4. Merrimac Phase Modulators are designed for high reliability and can be supplied
screened to meet specific military and space applications.
