Description
The ACPM-5251 is the dual-band power amplifier module with integrated directional coupler designed for UMTS Band 1 and Band 5 uplink transmission in the mobile handsets, data cards or dongles supporting WCDMA and/ or HSPA.
Features
- CoolPAM-5 circuit technology which supports 3 power/gain modes.
- active bypass (low power), mid power, and high power modes. CoolPAM is the stage bypass technology that enables very lower power consumption especially in the low and mid output power ranges. The active bypass technology added in the CoolPAM-5 further enhances the PAE at low output power range together with the exceptionally low quiescent current. It dramatically saves the average power consumption extending the talk time o.
