DESCRIPTION Ericsson GE’ s M-PD System Pe rsonal Radio is a high- quality , high-performance, two-way , FM, comm unicat ions uni t consis ting of a transmit/r eceiv e circuit with a frequency syn- thesizer cont rolled by a microprocessor .
• Channel Busy Lo ck Out : Personality information in- cludes the ca pability to preve nt the transmitter from op- erating on a channel where carr ier acti vity is present.
Assemble these part s into one unit according to the fol- lowing procedure and as sho wn in Figure 1 - M-PD Op erat- ing Controls and Accessories. 1. Screw the antenna or the RF te st connector In its receptacle. A clockwise turn will insert the antenna or RF test connector , while a counter clockwise turn will remove them.
2. U se the DTMF keypad or use the Recall T elephone Number key (RCL) to enter the digits of the te le- phone nu mb er . 3. Press the secondar y key and the n press the SEND key . An optional tone (sidetone) m ay be heard as each digit is transmitted.
Q202. The RF power output from Pin 2 of th e TX-Amp module A201 i s conne cted th rough a resist or atte nuator to Pin 1 of the P A module where it is appli e d to t he in pu t of the RF power amplifier stages. The RF power amplifie r stages amplify the input from the TX-Am p module to a typ ical power output le vel of 6 watts at Pin 5.
Synthesizer Circuit The Synt hesizer circu it co ntains P hase-L ock-l oop mod - ule (PLL) A 102, VCTCXO Referenc e Oscillator module A103, TX/RX V oltage Controlled Oscillator modul e (VCO) A106 and a Low Pas s Filter ampl ifie r (LPF). Refer to Fi g- ure 9 - Synthesizer .
CONTR OLLER CIRCUIT This co ntroller circuit consists of contr ol circuits and audio ci rcuits. Physi cally , this circuit consists of three cir- cuit boards as follo ws: • Contr ol Boar d • Signa.
Charger comb inations for charging the battery packs a re av ailable with char ge times of 1 hour , 3 hours and 16 h ours. A combination can be a single unit desk or a vehicular char ger . It can also be a wall mounted multiple charger . Charge Le vel A fully charged battery pack should provide a te rminal voltage greater than 7.
