Model: DT-620 FCCID: AXAROA1173201 Report Name: ERI2433.DOC3 of 28 1.0General Description 1.1Product Description The DT620 is a portable telephone which operates in the unlicensed isochronous PCS band from 1920Mhz to 1930Mhz. The frequency spacing of 8 separate channels is 1.25Mhz with the lowest channel centered at 1920.625Mhz. The DT620 operates on two power levels, 2mW and 90mW. The maximum peak transmit power level is 19.5dBm or 90mW. The Frequency reference for the handset is a 15Mhz Temperature compensated crystal oscillator (TCXO), D200. The portable transceiver is made up of two major circuit elements. A combination of digital and analog circuits provides a telephony user interface, with associated keypad, display, microprocessor and battery functions. The other part of the transceiver is the radio circuit. Radio circuits consist of synthesizers, mixer, amplifiers and filters. Also included is the QPSK modem(D20) function and related radio control functions for transmitting and receiving digital radio signals. Since the system is Time Division Duplexed the same frequency is used for both transmit and receive. After converting the TX signal to the frequency between 1920Mhz and 1930Mhz the signal is routed through a 3 pole bandpass filter, k L235, which removes the 1075.625Mhz to 1085.625Mhz image signals as well as the second LO at 1498.125 to 1506.875Mhz. A discrete filter follows the PA to reject harmonics of the output signal. 1.2Related Submittals / Grants There is a related submittal for this application.
