3.2 Power Amplifier Module (SKY77325, U302)

The SKY77325 Power Amplifier Module (PAM) is designed in a low profile (1.2 mm), compact form

factor for quad-band cellular handsets comprising GSM850/900, DCS1800, and PCS1900 operation.

The PAM also supports Class 12 General Packet Radio Service (GPRS) multi-slot operation.

The module consists of separate GSM850/900 PA and DCS1800/PCS1900 PA blocks, impedance-

matching circuitry for 50 input and output impedances, and a Power Amplifier Control (PAC) block

with an internal current-sense resistor. The custom BiCMOS integrated circuit provides the internal

PAC function and interface circuitry. Fabricated onto a single Gallium Arsenide (GaAs) die, one

Heterojunction Bipolar Transistor (HBT) PA block supports the GSM850/900 bands and the other

supports the DCS1800 and PCS1900 bands. Both PA blocks share common power supply pins to

distribute current. The GaAs die, the Silicon (Si) die, and the passive components are mounted on a

multi-layer laminate substrate. The assembly is encapsulated with plastic overmold.

RF input and output ports of the SKY77325 are internally matched to a 50 load to reduce the number

of external components for a quad-band design. Extremely low leakage current (2.5 A, typical) of the

dual PA module maximizes handset standby time. The SKY77325 also contains band-select switching

circuitry to select GSM (logic 0) or DCS/PCS (logic 1) as determined from the Band Select (BS) signal.

In Figure 3-5 below, the BS pin selects the PA output (DCS/PCS OUT or GSM850/900 OUT) and the

Analog Power Control (VAPC) controls the level of output power.

VBATT and VSENSE pins connect to an internal current-sense resistor and interface to an integrated

power amplifier control (iPAC¢‚) function, which is insensitive to variations in temperature, power

supply, process, and input power. The ENABLE input allows initial turnon of PAM circuitry to minimize

battery drain
