Product Description
The RF6288 is a high-power, high-efficiency dual-path linear amplifier module spe-
cifically W-CDMA transmitters used in UMTS mobile systems. This module uses a
balanced PA architecture which makes it load insensitive. The device is manufac-
tured on an advanced BiFET HBT process, and was designed for use as the final RF
amplifier stage in 3V UMTS handset equipment, spread-spectrum systems, and
other transmitter applications. The high band PA frequency coverage is 1710MHz to
1980MHz and the low band PA is 824MHz to 915MHz. The RF6288 has a common
analog bias control pin to reduce idle current at lower output power levels. In addi-
tion the RF6288 has implemented an integrated power coupler for each PA with
good directivity. The RF6288 is assembled in a 28-pin, 4.0mm x 7.0mm, laminate
package.
