Palo Alto, CAAgilent Technologies Inc. announced new CDMA power amplifier modules (3 mm x 3 mm) for handsets. Designated the WS1102 and WS1401, the modules are for operation in the 824-849 MHz and 1850-1910 MHz bands, respectively. (The WS1102 also operates in AMPS mode for backward compatibility with North American analog cellular systems.)
The devices feature the company's CoolPAM technology, which is optimized to reduce battery power consumption, allowing manufacturers to increase talk time by as much as 30 minutes. It is also designed to provide reliability, temperature stability, cool operation and ruggedness.
These amplifiers are designed to operate at +3.4 VDC (+3.2 VDC minimum) for compatibility with low-current consumption designs. They incorporate 50-ohm input and output matching networks, and are equipped with a control pin that sets operating parameters for highest efficiency when operating at low-output power levels. The new power amplifiers provide a power-added efficiency of 20 percent at +16 dBm. They are supplied in a 3 mm x 3 mm x 1.4 mm, 8-pin surface-mount module designed to assure high thermal conductivity, which minimizes temperature rise for higher reliability.
The WS1102 and WS1401 are priced at $1.30 each in moderate quantities. Sample and production quantities are available now through Agilent's direct sales channel. Click here for more information.
