RF / IF Integrated Circuits

Home > RF / IF Integrated Circuits

National's RF/IF integrated circuits include linear and logarithmic RF power detectors and DC-DC converters for RF PAs for smartphones, tablets, and other portable mobile devices as well as breakthrough RF-Sampling ADCs and high-performance frequency synthesizers/PLLs that revolutionize wireless infrastructure basestation, radar and lidar radio architectures.

Mobile RF Solutions

 

Infrastructure RF Solutions

Featuring LMVxxx & LMHxxx RF Power Detectors that accurately measure signals with high peak-to-average ratios such as those seen in WCDMA, HSPA, LTE, and WiMAX standards. Both logarithmic and linear output transfer curves including devices with frequency bandwidths ranging from 50 MHz up to 8 GHz and dynamic ranges higher than 40 dB with accuracy better than +0.2 dB as well as Root Mean Square (RMS) RF power detectors.

Signal Path

Other Complementary Products

 

Featuring ADC12Dxx00RF Direct RF-Sampling ADCs that sample beyond 2.7 GHz at up to 3.6 GSPS, replacing an entire IF-sampling or ZIF-sampling radio signal path subsystem of mixers, LO synthesizers, amplifiers, filters, and ADCs, while drastically reducing bill of materials (BOM) cost, design time, and board size, weight, and power.
