SA9504
DESCRIPTION
The SA9504 is an integrated receiver front-end for 900 MHz Cellular (AMPS) and 1.9 GHz PCS (CDMA) phones. This dual-band receiver circuit has low noise amplifiers and downconverters for both bands, and provides an elegant solution for RF-to-IF conversion. The two cascode LNAs have been designed to provide high gain with very low noise figures and high linearity. The downconverter portion is based on the Philips SA9502. There are two individual mixer blocks, each optimized for low noise figure and high linearity. The whole circuit is designed for low power consumption, high performance, and is compatible with the requirements for Cellular (AMPS) and PCS (CDMA) handsets. The circuit has been designed in our advanced QUBiC3 BiCMOS process with 30 GHz fT and 60 GHz fMAX.

FUNCTIONAL DESCRIPTION Mode selection
The SA9504 has several modes of operation for which the selection logic is defined in Table 1. 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. In order for the SA9504 to function correctly, a reset must be applied on first power-up. The whole circuit (LNAs and mixers) is powered down when control lines S0 and S1 are simultaneously held HIGH. An internal reset is applied upon releasing the circuit from power-down (on taking S0 = S1 from HIGH to LOW).
requirements. The Cellular FM mixer has a common single-ended RF input. 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, - PCS LO frequency doubler. 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 should be externally biased to power supply rail. The PCS and Cellular FM mixers have open collector differential IF outputs. 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.
LNA
The SA9504 has two LNAs, one for cellular FM, and one for PCS (CDMA). The LNAs have been designed for high gain, low noise figure and good linearity with low power consumption. External components can be used to match the LNA inputs for the Cellular and PCS bands. The LNAs employ a cascode output structure allowing high gain and excellent reverse isolation. The LNA outputs are internally matched to drive 50 external loads. The input and output return loss of better than 10 dB can be achieved in all modes.
Downconverter
The SA9504 has two mixers, one for Cellular FM, and one for PCS (CDMA). Each mixer is individually optimized for its specific

MODE SELECT LOGIC AND DC CHARACTERISTICS
The SA9504 chip has several modes of operation for which the selection logic is defined in the following table. Different mode selections require different portions of the circuit to be active. Modes from unlisted combinations of logic pins, are not valid.
POWER-UP PROCEDURE
In order for the SA9504 to function correctly as given in Table 1, the circuit must be reset on power-up as follows: To apply a reset, both S0 and S1 should be held HIGH simultaneously (hold time 100 ns minimum), and then released to a LOW state upon initially powering up the device.

Definitions
Short-form specification -- The data in a short-form specification is extracted from a full data sheet with the same type number and title. For detailed information see the relevant data sheet or data handbook. Limiting values definition -- Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information -- Applications that are described herein for any of these products are for illustrative purposes only. Philips Semiconductors make no representation or warranty that such applications will be suitable for the specified use without further testing or modification.
