Tyco Electronics of Lowell, Mass, USA has launched a new dual SPDT switch die for broadband applications that require high linearity, low insertion loss and high isolation. The M/A-COM MASW-008206-000DIE is intended for 802.11a, 802.11b/g, PC Card and access point applications and is optimized for 2.4GHz as well as 5.8GHz operation. With its low leakage current, the chip maximizes system linearity performance while reducing DC power consumption, the firm claims.

“This new switch is designed to exceed the needs of our WiMAX customers while providing competitive prices for cost-sensitive and space-constrained applications,” says product manager Mike Arrigo.

The new switch is suited to 802.11b/g applications with a 3V bias and is designed to have a low typical insertion loss of 0.7dB at 2.4GHz while achieving an isolation of 28dB and P1dB of 28dBm.Typical insertion loss at 5.8GHz is 0.9dB with an isolation of 25dB and P1dB of 28dBm. The new switch is fabricated using a low-cost 0.5-micron gate-length GaAs process and features full passivity for increased reliability, the firm says.

The MASW-008206-000DIE is available in wafer form and is priced at $0.19 for quantities of 100,000.
