Description

The SKY66002-11 linear power amplifier (PA) is a fully

matched surface-mount module developed for WCDMA

applications operating from 1900 to 2025 MHz. The device

meets the stringent spectral linearity requirements of

WCDMA femtocell applications with high power-added

efficiency. An integrated directional coupler eliminates the

need for any external coupler.

The GaAs MMIC contains all active amplifier circuitry, which

includes input and interstage matching circuits. An output

match into a 50 Ω load, realized off-chip within the module

package, optimizes efficiency and power performance.

The SKY66002-11 is manufactured with Skyworks InGaP

GaAs HBT process, which provides for all positive voltage

DC supply operation and maintains high efficiency and good

linearity. The primary bias to the device can be supplied

directly from any suitable power supply with an output of

4.2 V. Power down is achieved by setting the VEN pin to 0 V.

No external supply side switch is needed since typical “off”

leakage is a few microamps with full primary voltage

supplied from the main power supply.

The SKY66002-11 is packaged in a 10-pin, 3 x 3 mm Multi-

Chip Module (MCM), which allows for a highly

manufacturable low-cost solution.
