RFMD’s new RFHA104x series of high-power GaN broadband power transistors (BPTs) are optimized for military communications, commercial wireless infrastructure, and general purpose applications. These high-performance amplifiers achieve high power with high efficiency and flat gain over a broad frequency range in a single amplifier design.
Linear Technology Corp. introduces the LTC3864, a high voltage step-down DC/DC controller that draws only 40 µA quiescent current in standby mode with the output enabled in Burst Mode® operation. The 3.5 to 60 V input supply range is designed to protect against high voltage transients, to operate continuously during automotive cold crank and covers a broad range of input sources and battery chemistries.
RFMD's RFCA1008 is a high performance InGaP HBT MMIC amplifier designed with the InGaP process technology for excellent reliability. The heterojunction increases breakdown voltage and minimizes leakage current between junctions. A Darlington configuration is utilized for broadband performance.
The parts in RFMD’s new RF73xx series of high-power, high-efficiency linear power amplifiers are designed for use as the final amplification stage in 3 V, 50 Ω LTE mobile cellular equipment developed for E-UTRAN/LTE band operation. These parts are developed for 5 to 20 MHz LTE channel bandwidths.
Linear Technology Corporation introduces the LTC4226, a dual Hot Swap™ controller, enabling safe board insertion into live 4.5 to 44 V backplanes. The LTC4226 controls external N-channel MOSFETs to gently power up the board, avoiding sparks, connector damage and system glitches. A dual rate fault timer protects the MOSFET and system from long or damaging overcurrents.
Agilent Technologies Inc. introduced two new low-noise power sources. Members of the Agilent B2900A precision instrument family, the one-channel B2961A and the two-channel B2962A are revolutionary power supplies for precision low-noise voltage/current sourcing. They incorporate revolutionary performance and innovative sourcing capabilities beyond just a DC power source for every research and industry area.
Richardson RFPD Inc. announces immediate availability and full design support capabilities for a new dual, 14-bit analog-to-digital converter (ADC) from Analog Devices, Inc. (ADI). The AD9645 includes an on-chip sample-and-hold circuit designed for low cost, low power, small size and ease of use.
PMI Model No. FD-0518-10-812 is a 8.0 to 12.0 GHz frequency discriminator that provides a video output of 50 mV/GHz and has an accuracy of +/-200 MHz. The rise time is less than 20 nsec and operates into a 100 ohm video load. This model operates on +/-15 VDC and measures 2.0" x 1.8" x 0.5".
Richardson RFPD Inc. announces immediate availability and full design support capabilities for a new direct digital synthesizer (DDS) featuring an internal, high speed, high performance, 12-bit digital-to-analog converter (DAC) from Analog Devices Inc. (ADI). The AD9914 is a complete high frequency synthesizer capable of generating a frequency-agile analog sinusoidal waveform (sine wave) at up to 1.4 GHz.
