Introduction
NHD–4 is a dual mode handportable Cellular phone product for the North
American dual mode CDMA/AMPS system.
The transceiver consist of four modules: UI–flex, RF/system module,
battery pack and mechanics.
NHD–4 offers analog and digital mode full rate speech services defined in
IS–96 and in analog mode provides six power levels at a maximum power
level of 0.6W ERP (450mW into 50 Ohm load) in power class III. The
transceiver has a retractable antenna and a connector for external
antenna and accessories. The user communicates with the phone via
LCD–display, keyboard and some audible tones.
The transceiver will support an Analog PCMCIA Card.
NHD–4 can be connected to different accessories such as chargers,
holders, hands–free units, data–adapters and handset through the bottom
system connector.
