HILLSBORO, Ore. -- TriQuint Semiconductor Inc. here has broadened its portfolio of radio-frequency ICs for PCS and cellular band RFICs for CDMA cell phone applications
The TQ3132 LNA, designed specifically for cellular band CDMA/AMPS receive applications, and the TQ3632 LNA, designed specifically for PCS band CDMA receive applications, meet the requirements of both IS-95 and AMPS standards. With operating currents 30% lower thanpreviously available devices, the new ICs allow for either longer standby operation or smaller battery size for handsets, said TriQuint.
"These devices provide customers a low noise, low current and high IIP3 solution. There are several integrated advantages on-chip, which keep cost and size to a minimum," said Cathy Arb, product engineer in TriQuint's Wireless Division.
When used in combination, the LNAs provide a tri-mode
operation in the 800-MHz and 1,900-MHz bands. Both LNAs incorporate
on-chip switches, which select high, low, and bypass gain modes.
The TQ3132 and TQ3632, packaged in small SOT23-8 packages, are currently available from stock. Pricing for the TQ3132 CDMA/AMPS LNA is $0.97 and for the TQ3632 CDMA PCS LNA is also $0.97, in 1,000-piece quantities.
