TriQuint Semiconductor Unveils Passive GaAs and SiGe transmitter Circuits

Hillsboro, OR. TriQuint Semiconductor has introduced a series of passive GaAs couplers and splitters, in addition to a SiGe tri-mode, dual-band transmitter targeting cell phone and personal communications applications. The two passive components, when combined with TriQuint s SAW filters, duplexors, transmit and receive ICs, provide single vendor supply for all cell phone RF components. The coupler devices are also available in die form for integration into module assemblies. As the handset market continues to demand smaller and smaller form factors TriQuint is positioned to integrate major functional blocks into cost effective module solutions.

GaAs passive couplers and splitters Couplers perform power sampling and level sampling functions typically found in the transmit chain, while splitters provide power splitting functions typically found in the VCO chain of cellular handsets. A splitter allows the handset to function from one VCO for the receive and transmit chains, saving cost and board space.

Each product supports a particular communications standard including CDMA, AMPS, PDC, US PCS and WCDMA. Packaged in ultra-small 2 x 2 mm lead-less packages, these devices are designed for use in phone circuit-board applications or inclusion in module products. Both products are made using TriQuint s proprietary optimized passives process. This process exploits the superior substrate insulating properties of GaAs and TriQuint s proprietary thick metal planar processing to achieve inductor Q s at 1 GHz of 50. The exclusion of transistors in the passives process allows for fewer masking layers and the use of low cost wafer substrates resulting in a cost-effective integrated passives solution.

The TQ1200 through TQ1209 are each priced at $0.34 in 1000 piece quantities and TQ1303 through TQ1308 passives are priced at $0.40 in 1000 piece quantities.

SiGe tri-mode, dual-band transmitter

TriQuint s TQ7M35 tri-mode, dual-band transmitter integrates all transmit functions from the analog base-band output to the power amplifier input and is intended for CDMA/PCS/AMPS phones. When combined with the TQM7136 and TQM7636 power amplifier modules it provides a complete CDMA Tri-mode, dual-band transmit solution targeted for the growing U.S. CDMA marketplace. This is the first transmitter product announced by TriQuint s and Atmel s CDMA345TM joint development project. The complex functionality and excellent RF performance were achieved utilizing Atmel s low cost, leading-edge Silicon-Germanium (SiGe) semiconductor process.

The TQ7M35 maximizes phone talk time by offering low overall current consumption and the capability to selectively power-up individual circuit blocks. The RF performance-linearity, output power, and dynamic range--exceeds the requirements of the IS-95 standard simplifying the design-in process. Specifically, the high output power, linearity, and dynamic range of the TQ7M35 achieved using Atmel s low-cost, high-performance SiGe BiPolar process technology enables a lower cost transmit solution by easing the stringent requirements on downstream components. An on-chip auxiliary phase-locked loop with an active voltage-controlled-oscillator and a simple 3-wire, 4-bit serial bus interface for selecting TQ7M35 operating modes greatly simplifies the design-in process.

Strategic customer sampling has commenced and will continue through the scheduled start of high volume manufacturing release in Q4 2001. This CDMA transmitter is part of the CDMA product series being developed as part of the CDMA345TM joint development project with Atmel. The technology behind the CDMA345 TM product family has evolved through years of R&D and custom product development in the RF marketplace by both TriQuint and Atmel, and through the collaborative efforts of TriQuint and Atmel to jointly develop integrated circuit technology for the CDMA marketplace.

TQ7M35 Features/Specifications: · Supply voltage range down to 2.7V · 100dB of total dynamic range · Requires only one external synthesizer · 105 mA current consumption · Programmable output power: PCS Band +8dBm@54dBc ACPR, Cell Band +9dBm@54dBc ACPR · Power down capability · On-chip IF PLL · 3-wire (4 bit) bus programming · Small 5x5mm 32 pin package
