Adjacent Channel Power Ratio (ACPR) and Error Vector Magnitude (%EVM) Measurements
TIDA-00076: This reference design discusses the use of the TSW3085EVM with the TSW3100 pattern generator to test adjacent channel power ratio (ACPR) and error vector magnitude (EVM) measurements of LTE baseband signals. By using the TSW3100 LTE GUI, patterns are loaded into the TSW3085EVM which is comprised of the DAC3482, TRF3705, and LMK04806.
Wideband RF-to-Digital Complex Receiver-Feedback Signal Chain
TIDA-00074: This is a wideband complex-receiver reference design and evaluation platform that is ideally suited for use as a feedback receiver for transmitter digital predistortion. The EVM signal chain is ideal for high intermediate-frequency (IF) complex-feedback applications and contains a complex demodulator, TI’s LMH6521 dual-channel DVGA and ADS5402 12-bit 800-MSPS dual-channel ADC. By modifying the onboard filter components, the signal chain is configurable for a variety of frequency plans. The EVM also includes TI’s LMK04808 dual-PLL clock jitter cleaner and generator to provide an onboard low-noise clocking solution. The LMH6521 DVGA gain is controlled through the GUI or alternatively through the high speed connector with an FPGA.
Capacitor-based Backup Power Supply for PLC Modules Reference Design
TIDA-00500: TIDA-00500 is a reference design to provide power to load for short duration of time after a power interrupt has occurred. Traditionally Programmable Logic Controllers (PLCs) are equipped with a recharge battery source for alternative power. This battery source often suffers from drawbacks like complex charging topologies, charging time, periodic maintenance, and eco-hazards. In scenarios where PLCs need to be functional for a short duration of time after power interrupt, a capacitor based backup is a much simpler and more effective approach because of the higher power density in comparison to a standard battery-based solution.
