TriQuint Semiconductor Introduces Two TDMA Receiver Integrated Circuits for Cellular/PCS Phone Applications

These IS-136 Compliant Devices Feature 2.8 Volt Operation With Power Down for Longer Battery Life

December 6 1999

Hillsboro, OR. TriQuint Semiconductor, Inc. (Nasdaq:TQNT) today announced the introduction of its latest in a series of Gallium Arsenide (GaAs) TDMA-mode monolithic receiver ICs. The TQ5122, Cellular frequency band receiver, and the TQ5622, PCS frequency band receiver, are complementary devices designed for use in IS-136, TDMA, or equivalent wireless handsets. The TQ5122 and TQ5622 are low current devices which include a power down or "sleep" mode to extend both standby and talk times in wireless applications. Both devices include an LNA, mixer, LO Buffer, and IF buffer amplifier and operate from a single 2.8 Volt power supply. The TQ5122 and TQ5622 are designed to minimize the number of external bypass and matching elements to keep board space and cost to a minimum.

TriQuint Semiconductor, Inc. (Nasdaq:TQNT) today announced the introduction of its latest in a series of Gallium Arsenide (GaAs) TDMA-mode monolithic receiver ICs. The TQ5122, Cellular frequency band receiver, and the TQ5622, PCS frequency band receiver, are complementary devices designed for use in IS-136, TDMA, or equivalent wireless handsets.

The TQ5122 and TQ5622 are low current devices which include a power down or "sleep" mode to extend both standby and talk times in wireless applications. Both devices include an LNA, mixer, LO Buffer, and IF buffer amplifier and operate from a single 2.8 Volt power supply. The TQ5122 and TQ5622 are designed to minimize the number of external bypass and matching elements to keep board space and cost to a minimum.

The TQ5122 and TQ5622 each draw typically 12mA in the on state and less than 100(mu)A in the off state. Conversion gain is 18.5dB and 17.5dB respectively. Both have an Input Intercept point, IIP3, of greater than -9dBm and Noise Figures better than 2.8dB. They meet all electrical requirements for IS-136 phones.

Applications

The TQ5122 and TQ5622 are specifically designed for use in IS-136 TDMA phones, in both the US Cellular and PCS frequency bands. Steven Rupp, TriQuint Product Marketing Manager said, "With these devices, design engineers can easily implement a cost effective, reproducible tri-mode TDMA phone using minimum printed circuit board area. Customers will find these devices work well in the first prototype, often without additional design iterations."

Package

Both ICs are packaged in a small, inexpensive JEDEC QSOP-16 plastic package and are shipped in tape and reel format.

Price And Delivery

Unit price for either the TQ5122 or the TQ5622 is $2.43 in quantities of 1000. Evaluation boards and production quantities are available now.

Support

Technical support is available along with data sheets and evaluation boards. The TQ5122 and TQ5622 data sheets are available on TriQuint s website in pdf format at http://www.triquint.com/Wireless/Products/TQ5122/TQ5122%20revD.pdf and http://www.triquint.com/Wireless/Products/TQ5622/TQ5622%20rev-A.pdf respectively.
