Description

The SE2605L is a 2 GHz Microwave Monolithic Integrated Circuit

(MMIC) Power Amplifier (PA) with superior output power, linearity,

and efficiency. These features make the SE2605L ideal for

Wireless Local Area Network (WLAN IEEE 802.11n) applications.

The device is fabricated using SiGe BiCMOS technology. The

device is internally matched and mounted in a 20-pin, 4 x 4 mm

Quad Flat No-Lead (QFN) Surface-Mounted Technology (SMT)

package, which allows for a highly manufacturable low cost

solution.

A block diagram of the SE2605L is shown in Figure 1.The device

package and pinout for the 16-pin QFN are shown in Figure 2.

Signal pin assignments and functional pin descriptions are

described in Table 1.
