Using Calibration to Optimize Performance in Crucial Measurements
Texas Instruments (TI) expanded its RF portfolio today with the addition of high-performance RF gain blocks, down-converting mixers and a complex modulator that provide the industry’s best combination of power and performance. The new RF devices were demonstrated this week in TI's Booth 2041 at the International Microwave Symposium and complement TI's existing portfolio of transmit digital-to-analog converters (DACs), receive analog-to-digital converters (ADCs), IQ modulators, IF DVGAs, phase-locked loop (PLL) and RF synthesizers. For more information about the new RF gain blocks, down-converting mixers and complex modulator, visit www.ti.com/rfgainblocks-pr, www.ti.com/downconvertingmixers-pr and www.ti.com/complexmodulator-pr.
RF gain blocks
The new 3.3-V and 5-V RF gain block family offers a unique combination of broad frequency range, small footprint, high integration, high output 3rd intercept point (OIP3) and low power consumption to maximize design flexibility. The versatile devices can be used in many industrial, communications and defense applications, such as smart meters, test and measurement, wireless base stations, RF backhaul, repeaters, and phased-array radar.
Key features and benefits
-2-mm by 2-mm QFN package saves board space
-Integrated power down eliminates need for an external switch, which reduces bill of materials cost and saves board space.
The 5-V devices are available now, and evaluation modules (EVMs) are available for purchase today for US$49. The 3.3-V gain blocks will be in volume production in July 2014, and EVMs will be available for purchase later this month.
High performance, multi-channel receiver applications value high linearity, gain and wide tuning flexibility at the lowest power consumption. The new dual-channel down-converting mixer family matches the performance of existing solutions at half the power consumption. The mixers can be used in diversity receive, multi-antenna and high-performance applications, such as phased-array radar, wireless base stations, RF backhaul and repeaters, and test and measurement.
Key features and benefits:
High-performance transmitters require an optimized combination of power, linearity, phase noise and frequency range. The TRF3722complex modulator provides the best combination of these features and can be paired with the new down-converting mixers in high-performance applications, such as phased-array radar, wireless base stations, RF backhaul and repeaters, and test and measurement.
Key features and benefits:
Tools, pricing and availability
The TRF3722 up-converting complex modulator will be available later this month in a 7-mm by 7-mm QFN package for US$9.50 in 1,000-unit quantities. An EVM will be available to purchase in early June for US$199.
