SPECIFICATIONS
RF Carrier Frequency Range
692–716 MHz
Working Range
152.4 m (500 ft), minimum, under typical conditions; 487.6 m (1600 ft ) line of sight
NOTE: Actual working range depends on RF signal absorption, ref lection and
interference
Audio Frequency Response
45 to 15,000 Hz, ±2 dB. NOTE: Overall system frequency response depends on the
microphone element
Gain Adjustment Range
UC1B: –6 to 34 dB
UC2B: –6 to 26 dB
Modulation
±45kHz deviation compressor-expander system with pre-and de-emphasis
RF Power Output
UC1B: 50 mW effective radiated power , typical
UC2B: 20 mW effective radiated power , typical
Dynamic Range
>100 dB, A-weighted
Receiver Audio Output Level (Maximum)
+5 dBu typical, unbalanced output
+14 dBu typical, balanced output
RF Sensitivity
UC4B: –108 dBm at 12 dB SINAD
Image Rejection
90 dB typical
Spurious Rejection
70 dB typical
Ultimate Quieting (ref. 45 kHz deviation)
>100 dB, A-weighted
Audio Polarity
Positive pressure on microphone diaphragm (or positive voltage applied to tip of
WA302 phone plug) produces positive voltage on pin 2 with respect to pin 3 of
low impedance output and the tip of the high impedance
System Distortion (ref. ±45 kHz deviation, 1 kHz modulation)
0.4% T otal Harmonic Distortion typical
Power Requirements
UC1 B , U C2B: 9 V a lkalin e batt e ry (D u racell MN1604 recom mended); Nicad optional
UC4B: 15 Vdc , 600 mA 50/60 Hz
Power Consumption: 600 mA x 15 V , maximum
