Switch isolates Bluetooth from WLAN

Santa Clara, CA —With 35dB isolation at one of its ports, NEC’s new UPG2150T5L SP3T (Single Pole Triple Throw) switch offers a unique solution for isolating Bluetooth from 802.11b/g. This GaAs MMIC switch operates at 0.5 to 2.5GHz and is housed in a low-profile 12 pin TSQFN package. Measuring 2mm square and 0.37mm high, it offers a 55% smaller footprint and a 58% reduction in height over industry-standard 3x3x0.9mm QFN packages. This makes it well suited for size-constrained designs such as thin PCM cards and modules.

Typical insertion loss is 0.5 dB at 2.5 GHz. Input-to-output isolation is typically 18 dB at 2.5 GHz (Antenna to RF1, RF2), and 35 dB at 2.5 GHz (Antenna to RF3). Output power at 1-dB compression is typically +31 dBm at +2.85VDC (Antenna to RF1, RF2) and +25 dBm at +2.85VDC (Antenna to RF3).

The UPG2150T5L is priced at $0.55 each in 100,000-piece quantities. It is sampling now. Evaluation boards are available.Click here for the data sheet.
