Boring old stuff from the FCC site. Ask Jon. ---- Applicant: SANYO Electric CO., LTD. Transmitter Type: AEZSCP-5150 EXHIBIT 1 / 1 TECHNICAL DESCRIPTION This transmitter has been specially designed for the Domestic Personal Communication Service(CDMA) and the Domestic Cellular Radiotelephone Communication Service (AMPS). [PCS mode] The rated maximum power output for PCS is 0.2 watts with the capability of reducing the maximum power in a step of 1 dB on command from the base station. The transmitter output is confirmed correspond to the received power level of the mobile station. Each power level is maintained within +2 /-4 dB of its nominal level over the temperature range from –30 to +60 degrees centigrade and +14 –14% change of the supply voltage. This transmitter operates in the frequency range of 1851.250 MHz to 1908.250 MHz. The frequencies are generated by Phase Locked Loop Frequency Synthesizers, which are controlled by the closest base station in the system. The handset causes the frequency stability of carrier according to the frequency from the base station to become less than + 150 Hz. The transmitter is equipped with a voice processor and a Codec that are included in IC210 MSM5105. The Codec (that is included in IC210 MSM5105) samples a voice signal and a Voice processor codes EVRC or 13K voice data packet. And MSM formats the modulated signals with a voice data packet. The modulation is the Quadrature modulation. The I and Q signals are shaped by the filters whose function is included in MSM. The signals are transformed to BBA (Base Band Analog processor) (IC20). The D/A Converters, that are included in IC210 MSM5105, generate analog I and Q signals. The low pass filters shape the analog I and Q signals to limit Band width 1.25MHz. ----
