M/A-COM lead-free SPDT GaAs switch targets WLAN apps

M/A-COM Inc., a business unit of Tyco Electronics and a leading provider of wireless radio frequency (RF), microwave and millimeter wave components, has announced a new lead-free low-loss SPDT GaAs switch.

The MASWSS0115 provides low-loss switching for the transmit/receive function in 802.11b WLAN applications and for low power general-purpose RF applications in a small SOT-363 (6-lead SC-70) package. The MASWSS0115 may be used for other low and medium power switching applications from dc to 3GHz.

The MASWSS0115 provides switching of the RF common port between two additional RF ports. This switch is a lead-free version of the company's low cost SW-485. With its low loss of 0.35dB at 2.4GHz and linearity at 20dBm input power, the lead-free MASWSS0115 and SW-485 are suitable for 802.11b T/R switches. The MASWSS0115 and the SW-485 are appropriate for low power handset and basestation applications that require low insertion loss, excellent return loss, and low cost.

Both switches come in a small SOT-363 package making a transition to lead-free easier for customers. They work with positive control voltages as low as 2.3V, provide low insertion loss (0.35dB at 2.4GHz), excellent VSWR (1.1:1 typical), and good isolation (>20dB).

The new MASWSS0115 switch and corresponding sample test boards are available for immediate delivery through M/A-COM's worldwide direct field sales force and through authorized distributors. The MASWSS0115 is priced below 18 cents each in quantities of 50,000 and is available on 3,000 piece reels.
