RFMW Ltd. announces design and sales support for two power amplifier modules supporting 5 GHz Wi-Fi enabled CPEs, routers, pico cells and femto cells. The Qorvo RFPA5522 supports applications from 5.18 to 5.925 GHz with bias configurable to 5 or 3.3 V operation. The Qorvo RFPA5542 extends operation from 4.9 to 5.925 GHz and is optimized for the least number of external components on compatible reference designs.
RFMW Ltd. announces design and sales support for API Technologies’ 305W single channel rotary joint. The API rotary joint is used to transmit RF energy from a stationary RF source to a rotating RF line. The 305W operates from DC to 12.4 GHz through type N coaxial connectors. VSWR is as low as 1.15:1. Rotary joints have inherently low insertion loss as evidenced by the 305W with loss ranging from <0.2 dB below 6 GHz to <0.3 dB below 12.4 GHz.
Richardson RFPD Inc. announced the availability and full design support capabilities for a new dual differential, single pole double throw RF switch. The PE42920 DDSPDT RF switch is a broadband (10 kHz to 6 GHz) and low loss device that enables the switching of two independent differential signals. This device consumes less power than active differential switches. It has high isolation between same-channel inputs, as well as opposite active channels.
RFMW Ltd. announces design and sales support for the Qorvo TGA2227, a 2 to 22 GHz low noise amplifier fabricated on Qorvo’s TQGaN15 GaN on SiC process. The Qorvo TGA2227 can also be used as a driver with >15 dB of small signal gain or a general amplifier with >20 dBm P1dB. With a nominal drain voltage of 8 V, the TGA2227 can be biased over a wide range of voltages with little impact on noise figure and gain
Keysight Technologies Inc. introduced a wireless power transfer analysis option for its E5072A, E5061B, and E5063A ENA series network analyzers. With this software option, the ENA series network analyzers are now able to effectively address the needs of emerging wireless power transfer (WPT) markets. A key factor in designing WPT devices is the performance of the power transfer efficiency between coupled coils and resonators.
The TAT7472A1F is a 75 Ω RF amplifier designed for CATV use but capable of operation up to 1218 MHz, making it suitable for DOCSIS 3.1. It contains two separate amplifiers for push-pull applications and is fabricated using 6-inch GaAs pHEMT technology. Each amplifier contains on-chip active biasing, with bias current set points that are adjustable with a single resistor from the input to ground. Typical supply voltage for the TAT7472A1F is +5 V.
RFMW Ltd. announces design and sales support for Qorvo's TQL9092, a flat-gain, high-linearity, ultra-low noise amplifier (LNA). The TQL9092 provides 2 dB (peak-to-peak) gain flatness from 1.5 to 3.6 GHz.Typical gain is 22.6 dB and OIP3 is 39.5 dBm at a 65 mA bias setting. Noise figure at this setting would be 0.6 dB. The TQL9092 can be biased from a single positive supply ranging from 3.3 to 5 volts.
M/A-COM Technology Solutions Inc. announced its MAAM-011169 12 V CATV push-pull infrastructure amplifier designed to meet DOCSIS 3.1 and C-DOCSIS standards.The MAAM-011169 delivers 46 dBmV per channel output power with 25 dB gain and is optimized for very low distortion and high linearity in a 75 ohm push-pull amplifier circuit. It provides excellent input and output return loss over the 45 to 1200 MHz bandwidth whilst delivering superior thermal performance.
Passive Plus Inc. now offers a low ESR/ESL EIA capacitor series. These multi-layer capacitors have been developed for high-Q and microwave applications, exhibit NP0 characteristics and are RoHS compliant. Values range from 0.1 pF to 1000 pF and 25 to 1000 V. Data sheets, along with S-Parameter and modeling data, for each of the case sizes are on the PPI website.
RFMW Ltd. announces design and sales support for the 0.5 W QPA9119, a high linearity amplifier from Qorvo. Covering 400 to 4200 MHz, the Qorvo QPA9119 has 17 dB of gain, a P1dB of 27.2 and offers +44 dBm OIP3. The QPA9119 draws only 137 mA from a 5 V supply and is ideal for repeaters and distributed amplifier systems. Designed to support both TDD and FDD systems, the Qorvo QPA9119 comes in a 3 x 3 mm QFN package.
