AJAV-6781

WCDMA/HSPA Band 1 and Band 8 mm x mm Dual-Band Power Amplifier Module

The AJAV-6781 is a complete, high-performance power amplifier for WCDMA and HSPA wireless communications. Based on a unique, patented architecture, the AJAV-6781 integrates circuitry for Tx filtering, RF coupling, power regulation, input and output matching, and power control. The PA power amplifier is powered by a connection to the battery and is implemented in a standard CMOS process.

The AJAV-6781 contains integrated directional couplers, 50-ohm input and output matching networks and RF input and output DC blocking capacitors. All of these functions are integrated in a 15-pin surface-mount leadless package of 3 mm x mm form-factor and 0.9-mm thickness, so it can minimize the number of external components.

The integrated LB and HB directional couplers are daisy-chained internally. One coupler input port and one coupler output port are shared by the both bands. The AJAV-6781 has integrated on-chip Vref and on-module bias switch, so the external LDO regulators and switches for external Vref are not required. It also makes the PA fully digital-controllable by the baseband chipset. The Ven pin turns the PA on and off by the digital control signal. All of the digital control input pins, such as the Ven, Vmode0, and Vmode1, are fully CMOS compatible down to the 1.8V logic.

Thin Package 0.9mm typ. 15-pin surface mounting package Small 3 x mm package size Internal 50 ohm matching networks for both RF input and
output 3-mode power control with Vmode0 and Vmode1 Compatible with APT application Low average current High capacity CMOS process High-performance 3G power amplifier.

UMTS Band 1 1920 ~ 1980 MHz UMTS Band 8 880 ~ 915 MHz WCDMA, HSPA and HSPA+ compliant Integrated Tx filtering Delivers best noise in the industry Integrated coupler and Isolation ports for daisy chain Green - Lead-free and RoHS compliant
