Introduction
NHP–4 is a CDMA mode handportable Cellular phone product for the
North American CDMA system.
NHP–4 offers digital mode full rate speech services defined in ANSI
J–STD–008. The transceiver has a retractable antenna and a connector
for accessories. The user communicates with the phone via LCD–display,
keyboard and some audible tones.
NHP–4 can be connected to different accessories such as chargers,
holders, hands–free units, data–adapters and handset through the bottom
system connector.
Module Description
The transceiver electronics consist of the Radio Module (RF + Baseband
blocks) and the UIF Module. The UIF Module is connected to the Radio
Module with a 30 pin connector. BaseBand blocks and RF blocks are
interconnected with PCB wiring. The Radio Module receives power from
the Battery via a 4 pin connector located at the bottom of the PCB. The
Transceiver is connected to accessories via a bottom system connector
with charging and accessory control.
General Information
The Radio Module provides the MCU and DSP environments, Logic
control IC (CDMA ASIC), memories, audio processing and RF control
hardware (CDRFI). On board power supply circuitry delivers operating
voltages for both BaseBand and UIF modules.
The UIF Module is a flex circuit with 4 blocks–– keyboard, display, buzzer,
and audio (earphone and microphone). The buzzer block contains a high
current amplifer circuit to drive the buzzer. LEDs are provided for
keyboard and LCD back lighting.
The RF block is designed for a hand portable phone, which operates in
CDMA PCS systems. The purpose of the RF module is to receive and
demodulate a radio frequency signal from the base station and to transmit
a modulated RF signal to the base station. The RF parts are designed for
power class II.
The system part provides MCU and DSP environments, memories, audio
processing, and RF control hardware. On board power supply circuitry
delivers operating voltage for both system and RF parts.
