After Sales THA–4S System Module Technical Documentation Charging Control The charging circuit is fully controlled via software determined from Battery Size Indicator and Battery TEMPerature A/D converter inputs. The BTEMP is derived from an incorporated thermistor in the battery pack and converted to real temperature via a table in SW, which decides where the critical limits for charging is. The BSI resistor is built in the battery package and designed to give an A/D reading of 344 – (1.
After Sales THA–4S Technical Documentation System Module Audio Circuit Description Transmit (TX) Signal Path The TX audio signal is processed in the N_ANTIC and fed, via the MOD line, to the synthesizer.
After Sales THA–4S System Module Technical Documentation RF Circuit Description Receiver The receiver is a dual–conversion superheterodyne using two intermediate frequencies, 86.85 MHz and 450 kHz. The RF signal from the duplexer RX port is applied to the Low Noise amplifier. The amplifier is realized with transistor V200. Amplifier stage input matching is accomplished by C201 and L217. R200 and R201 are used for biasing. Output matching is carried out by L216, R211 and C325.
After Sales Technical Documentation THA–4S System Module RX Synthesizer The first injection frequency (1st LO) is obtained from a voltage controlled oscillator (VCO) V205. The VCO output signal is amplified by transistor V204 and fed to the receiver mixer via Z05. The injection level required by the receiver mixer is nominally +3 dBm. In addition, the signal is fed through C230 to a buffer amplifier and divider chain in the synthesizer circuit N202 and via R297 to an amplifier V212 in the TX synthesizer.
After Sales THA–4S System Module Technical Documentation The VCO signal is amplified by buffer amplifier V204. This amplifier produces +3 dBm to the first mixer via Z06. The same buffer produces a level of –15 dBm to the divider–buffer in N202 and –10dBm to the amplifier V212 in the TX synthesizer via C230.
After Sales Technical Documentation THA–4S System Module The module is based on GaAs technology and does not require any negative gate voltage, giving a simpler bias circuitry and safer construction.
After Sales THA–4S System Module Technical Documentation The transceiver unit is equipped with an AFC function, i.e. it uses the incoming receive signal from the base station as a frequency reference. The control loop consists of the receiver, the IF counter in the modem (D100), CPU (D101), an 8–bit D/A converter in the modem and the VCTCXO, which is used as a reference oscillator for the synthesizer.
