VMP-2R Series VECTOR I&Q MODULATORS 10 to 1000 MHz / Narrowband QPSK / For MSK Systems / 10% Bandwidth / Hermetic PC Package PRINCIPAL SPECIFICATIONS GENERAL SPECIFICATIONS Model Number Center Frequency, fo, MHz Usable RF Bandwidth VMP-2R-***B 10 - 1000 10% of fo For complete Model Number replace ***with desired Center Frequency, fo in MHz. RF Input: Modulation Inputs: VSWR: Impedance: Insertion Loss: +10 dBm, nom. 0 dBm max. 1.5:1 max. 50 Ω nom. 12 dB max. (below modulation input) Modulation Accuracy (measured @ 4 quadrants, 0 dBm input) General Notes: 1. A vector modulator is used to phase modulate an RF carrier with complex analog signals. 2. Merrimac Vector Modulators consist of a quadrature hybrid and an in-phase power divider. 3. Units in the VMP-2R series are capable of modulating the carrier at up to 10% of the RF bandwidth. 4. These vector modulators comply with the relevant sections of MIL-M-28837 and may be supplied screened for compliance with additional specifications for military and space applications requiring the highest reliability. Amplitude Balance: Phase Balance: Carrier Isolation: Dynamic Range (output): Operating Temperature: 1 dB ± 5° 35 dB typ. 20 dB nom. -- 55° to +85°C AVAILABLE OPTIONS Close tolerance phase and amplitude balance versions are available in custom designs. Units with higher center frequency (e.g.,1500 MHz to 3 GHz) are available in the VMP-2S series. Meri-Pac R-Package NOTES: 1. Tolerance on 3 place decimals ±.010(.25) except as noted. 2.
