INTEGRATED CIRCUITS SA9503 Dual-band, CDMA/AMPS LNA and downconverter mixers Objective specification Supersedes data of 1999 Jul 06 1999 Jul 29 Philips Semiconductors Objective specification Dual-band, CDMA/AMPS LNA and downconverter mixers SA9503 DESCRIPTION Downconverter typical performance The SA9503 is an integrated CDMA/AMPS low noise amplifier (LNA) plus a downconverter, for both the 900 MHz Cellular band and the 1.9 GHz PCS band. The LNA incorporates 5 settings of digitally selected stepped gain in the Cellular band and in the PCS band. One of the modes (high linearity mode) in each of the Cellular and PCS bands, includes a high IP3 setting in order to meet the 1-tone CDMA desensitization test. The gain, noise figure and IP3 for the remaining 4 low current modes in the Cellular band, are designed in order to have sufficient separation between the antenna power levels at which the LNA gains are changed, based on multi-tone interference levels. A 3 dB overlap is allowed in the antenna power levels for the adjacent modes. Table 1 indicates a typical scenario.

Each one is individually optimized for their specific requirements. The Cellular CDMA and FM mixers have a common single-ended RF input. Mode selection The SA9503 has several modes of operation for which the selection logic is defined in Tables 2 and 3. Different mode selections require different portions of the circuit to be active. Modes from unlisted combinations of logic pins are not permitted. The LNA and downconverter together can be programmed to operate in the PCS or cellular bands using the PCS/CEL logic input pin, and in CDMA or FM modes using the CDMA/FM logic input pin. The PCS mixer’s RF input port is differential, and requires an external balun when used with a single-ended source. Both the PCS and the Cellular mixer RF inputs should be AC coupled. Local oscillator drive for the mixers is provided through pins CEL LO_IN and/or PCS LO_IN. The local oscillator inputs are single-ended, AC-coupled. The CEL LO_IN signal is internally buffered to drive the following: – (Tx) LO output buffer, – cellular FM mixer, – cellular CDMA mixer, – PCS LO frequency doubler. The LNA can be set to four different gain values and one special high linearity setting. Thus, the LNA can be programmed into five different modes with associated gain, noise figure, and input IP3, using the S0, S1, and S2 control lines. The whole circuit (LNAs and mixers) is powered down when control lines S0 = 1, S1 = 0, and S2 = 0. It is also possible to independently switch off the LNAs and keep the mixers on, as shown in Table 3. LNA In the PCS mode, mixer LO drive can be either direct (PCS LO_IN) or through the frequency doubler after CEL LO_IN. The mixer local oscillator signal is made available externally via the (Tx) LO output buffer for potential use elsewhere in the radio. For example, this signal typically can be used with the transmitter circuitry. The (Tx) LO output buffer can be powered down independently, using the (Tx) LO_ENABLE logic input. The (Tx) LO output buffer has open collector differential outputs which are internally biased to VCC2 supply rail. External components can be used to match the LNA inputs, and if required, the outputs, for the Cellular and PCS bands. The input and output return loss of better than 10 dB can be achieved in all modes. For Cellular band FM, only the CEL_1 mode is required for the LNA. For CDMA, LNA modes CEL_1 and PCS_1 are used for normal operation, as they have the highest gains and lowest noise figures. For higher levels of multi-tone interference, other modes with lower gains are to be used. The high linearity CEL_L and PCS_L modes are used when there is a very strong adjacent channel interference, while at the same time the mobile is transmitting close to its full power. The high linearity is required in order to reduce the cross modulation of the LNA from the mobile’s transmitter, in the presence of strong adjacent channel interferer. The maximum transmitter power leakage which can be tolerated at the LNA input is approximately –30dBm to meet the single tone desensitization requirements. The cross modulation power can be derived from: The PCS and Cellular CDMA mixers have open collector differential IF outputs. The two IF outputs can either supply two separate IF filters, or they can be connected together externally for use with one common receive IF filter. The differential IF outputs must be biased at the supply voltage through external inductors that may also be part of the matching circuit to the SAW filter. The cellular band FM mixer also has a differential open collector IF output. Cellular band: (2 × PTX + PJAMMER – 8) dBm (2 × PTX + PJAMMER – 10.5) dBm PCS band: The LNA requires less than one hundred microseconds to settle when it changes from one mode to another. This is expected to have insignificant impact on the CDMA frame error rate.
