SiGe Semiconductor, Inc. announced two new power amplifiers that are designed to provide manufacturers with the lowest cost route to developing WiFi systems. The SE2537L and SE2581L power amplifiers (PAs)) aim to simplify development and reduce cost of discrete WiFi implementations in client access applications including laptop computers, gaming systems, small office and home based access points.
When used in combination, the power amplifiers can reduce the system bill of materials by as much as 30 percent compared to current solutions.
The SE2537L is a 5GHz power amplifier and the SE2581L is a 2.4GHz power amplifier. The combined solution of SE2537L and SE2581L integrates a digital interface that simplifies board design by eliminating the need for analog reference voltages. The integrated power detector in the SE2581L offers an input port for a coupled signal from the 5GHz output line, offering a single detector output for both bands. The company reports that this is an industry first for discrete solutions. This feature removes the need for an external coupler.
Systems based on the SE2537L and SE2581L will be capable of +20dBm in 2.5 GHz and +19.5 dBm at 5 GHz. The SE2581L, which is a feature-enhanced version of SiGe's widely used SE2527L, also includes an integrated power detector with 20 dB of dynamic range. The SE2537L and SE2581L are sampling now. As a pair these devices are priced at US $1.50 in 10k unit quantities.
