RF power transistor delivers 2500 W
The ART2K5TFUS and ART2K5TFUG power transistors from Ampleon amplify signals from 1 MHz to 400 MHz.
Optimize RF signal quality in 5G power amps
For 5G system performance, obtaining and maintaining the right balance of requirements for high power, power-added efficiency, and signal fidelity is critical. CCDF and PAPR measurements provide insights to help power amplifier designers achieve that goal. While all parts of the 5G RF signal chain contribute to overall system performance, the transmitter power amplifier (PA)…
Four-port switch lets you connect antennas to radios and test equipment
Signal Hound announced the addition of the RFS44 to its expanding product line. This powerful, ultra-fast antenna switch is in stock and available to Order Now. The RFS44 is a single pole four-throw (SP4T) absorptive solid state switch. Using silicon-on-insulator (SOI) technology, the RFS44 provides RF switching across four ports at up to 44 GHz.…
How GaN PAs in 5G radios push test requirements
Proper PA development, validation, and characterization are important because a PA often accounts for a significant portion of a transmitting device’s power consumption.
Mixer converts 20 GHz to 80 GHz frequencies down to IF
mmTron Inc. announced an innovative active mixer providing frequency conversion from 20 to 80 GHz. In addition to its bandwidth, the TMC170D stands out with 0 dB average conversion loss across the band with an LO drive of only 0 dBm. The InP semiconductor-based design achieves RF and LO coverage from 20 to 80 GHz…
Choose a 5G base station’s PA bias control circuit
Bias control of PAs is crucial to ensure optimum radio performance under all conditions. Current sensing and temperature sensing provide the feedback needed to control the PA bias. The choice of sensing and biasing circuits brings design trade-offs. 5G base station power amplifiers (PAs) need biasing using a separate bias controller to maintain optimum performance…
