Texas Instruments introduces industry's most highly integrated, full-duplex IF transceiver for wireless backhaul applications
"Microwave equipment manufacturers are looking for ways to help reduce the capital and operating expenditures of their service provider customers and the highly-integrated TRF2443 can help to meet that requirement," said David Briggs, general manager of TI's Radio products group.
Key features and benefits of the TRF2443
-Integration of more than 15 functional blocks enables designers to achieve 40 percent board space savings over discrete implementations. Functional blocks include:
-Programmable baseband amplifiers
-Intermediate Frequency (IF) amplifiers
-Analog and digital variable gain amplifiers
-Quadrature modulator and demodulator
-Programmable baseband low pass filters
-Analog-to-digital converter (ADC) buffers
-XPIC output amplifier and receiver
-Transmit (Tx) OIP3 of 29.5 dBm and receive (Rx) third order input intercept point (IIP3)of 9.5 dBm allows for more complicated modulation schemes and increased data throughput
-Programmable baseband low-pass filters provide flexibility to handle signals with different bandwidths and help to remove unwanted interferer signals
-Integrated Tx/Rx synthesizers eliminate the need for complicated external local oscillator circuitry, simplifying design
-Automatic DC offset calibration eases design implementation The TRF2443 broadband IF transceiver is the latest addition to Texas Instruments' high-performance RF product line for wireless communications, including: TRF3703 quadrature modulator, TRF3710 quadrature demodulator and TRF3761 RF synthesizers. Wireless infrastructure customers can accelerate time-to-market by taking advantage of TI's high-performance signal chain solutions that include market-leading analog-to-digital converters, such as ADS62P25, and digital-to-analog converters, such as DAC5662.
Availability and pricing
The TRF2443 device is available in a 14 mm x 14 mm QFP package and is priced at $24.00 in 1000-unit quantities.
