Product Features.

Full interface compatibility with existing fixed and rotary wing aircraft "wired" intercoms (both analog and digital). To address joint service compatibility, active, internal circuitry matches impedance and audio levels for different platforms and their variants (eg.: H-46D/E, H-53E, and H-60, C-130, C-5B, C-141, C-17A, UH-1).

Full compatibility of the crewman's AWIS portable radio with the SPH-4B, HGU-55/P, HGU-84/5P, and other "mil-spec" headsets/helmets with low impedance microphones and speakers including ANR-equipped headsets.

The lightweight crewman's AWIS radio is fully compatible with BDU's, flight suits, survival vests, and MOPP-4 ensembles.

In the "crew carry-on" configuration, interface to aircraft requires no airframe modifications. Communications hardware (Aircraft Interface Unit [AIU]) is not platform specific to simplify logistic support. Platform compatibility is accomplished through the AIU interconnect cables to the aircraft ICS and +28V.

500' + operating range (wireless crewman-to-aircraft interface unit (AIU), AIU-to-wireless crewman) with AIU positioned in the aircraft (0.1W RF output/50_). Operating range with AIU repeater in open terrain is approximately 2000'.

Operational compatibility has been validated with air and surface search radar systems: SPS 48; SPS 49; SPS 64, SPS 67 and SPY-1D.

2.400-2.483GHz configuration: Spread spectrum, direct sequence, time division multiple access (TDMA). Supports six, 6-member crews operating simultaneously, in a tight 1000' circle.

 User selectable "hot mic", push-to-talk operation. VOX option available.

Power for the AIU/AIC-xx interface can be taken from aircraft or APU-supplied +28V (<0.5A); spike protection to 600V is provided. Accommodation for single-use batteries for emergency power is provided. Rechargeable, sealed lead acid, or Li Polymer batteries are available.

Plug-in module battery pacs for crewmen's wireless ICS unit (8, single-use, AA, alkaline batteries, or Li Polymer rechargeable).

Battery pac duty cycle (when interfaced to low impedance speakers/microphone):

high demand drain rate ("hot mic" transmit/large amount of intra-crew communications): 5 hours

average demand drain rate (push-to-transmit/low amount of intra-crew communications): 10 hours

Audio (voice) signals are encoded into a robust digital format. Microprocessor-controlled squelch.

Speech sidetone produced through Aircraft Interface Unit (AIU), versus "locally" generated.

Y2K compliant.
