SPECIFICATIONS

RF Carrier Frequency Range

662-692 MHz

Working Range

U1, U2: 152.4 m, minimum, under typical conditions; 487.6 m line of sight NOTE: Actual working range depends on RF signal absorption, reflection and interference

Audio Frequency Response

50 to 15,000 Hz, ±2 dB. NOTE: Overall system frequency response depends on the microphone element

Gain Adjustment Range

U1: 0 to 40 dB U2: 0 to 26 dB

Modulation

±45 kHz deviation compressor-expander system with pre-and de-emphasis

RF Power Output

U1, U2: 10 mW maximum

Dynamic Range

>110 dB, A-weighted

RF Sensitivity (Typical)

U4S U4D

-110 dBm

12 dB SINAD

-105 dBm

30 dB SINAD

Image Rejection

100 dB typical

Spurious Rejection
