Last week the IEEE MTT International Microwave Symposium took place in Tampa, FL. If you weren’t able to make the Expo, here are some products making news.
Skyworks boasted best-in-class noise figure (NF) for its ultra-low noise amplifiers (LNAs) for cellular infrastructure, wireless connectivity and broadcast communication applications.
The SKY67150-396LF and SKY67153-396LF are optimized for 300 – 2200 MHz and 700 – 3800 MHz respectively. For the SKY 67153x, evaluation board NF is specified at: 0.25 dB @ 849 MHz; 0.35 dB @ 1850 MHz; 0.50 dB @ 2500 MHz; and 0.70 dB @ 3600 MHz. Output third-order intercept performance (OIP3) is better than +34 dBm over 700 to 3800 MHz. For the KSY67150x, the evaluation board NF is 0.23 dB @ 849 MHz, and OIP3 performance is +39 dBm.
Both devices feature an adjustable supply current from 30 to 100 mA with flexible bias voltage: 3 to 5 V. They are housed in 2 x 2 millimeter, 8-pin, dual flat no-lead package. Internal active bias circuitry provides stable performance over temperature and process variation. The LNA family uses a common layout with band-specific tuning and offers the ability to externally adjust supply current for system-level optimization.
Diamond Microwave extended its range of GaN-based solid-state power amplifiers (SSPA) to include a 2 – 6GHz model that can be operated in either pulsed or CW mode. At IMS2014, the company released provisional data for the unit: 100W peak power in pulsed mode at 2GHz and an average power capability of 50W across the full band. The amplifier measures 120 x 100 x 20mm (excluding the heat sink).
API Technologies Corp. introduced a line of Gallium Nitride (GaN) drivers for applications requiring high levels of gain and output power in commercial, military, medical, and industrial applications.
The drivers are manufactured in the United States using thin and thick film technologies, as well as surface mount technology (SMT), in a hermetically sealed package.
At IMS 2104, Anritsu Company announced enhancements to its VectorStar MS4640B VNA family and introduced the ShockLine vector network analyzer (VNA) series.
Consisting of three instruments with operation up to 40GHz, the ShockLine series is aimed at budget-conscious and educational users for testing passive devices. See extended coverage of the ShockLine VNA here.
Enhancements to the VectorStar included the MN469xC 4-port test set and optoelectronic measurements application (that can characterize magnitude and phase of E/O and O/E devices up to 65 GHz). The company claims that the MN469xC makes the VectorStar the only 4-port solution to provide high-quality S-parameter measurements down to 70 kHz.
Texas Instruments (TI) introduced the LMX2492, a 14-GHz fractional-N phased-locked loop (PLL) with advanced frequency modulation. The company claims that the LMX2492 PLL offers the industry’s best noise performance at -227 dBc/Hz normalized PLL noise.
The device supports a 200-MHz phase frequency detector, a 5-V charge pump supply and operates across 500 MHz to 14 GHz. The LMX2492 is offered in industrial and automotive grade (class 1) for military and automotive radar, microwave backhaul, communications, and test and measurement applications. The LMX2492 is housed in a 4x4mm 24-pin WQFN package. It is priced at US$8.75 in 1,000-unit quantities. More information: product datasheet.
Avago Technologies announced four new RF power amplifiers (PAs) for small cell base transceiver station (BTS) applications and line of LTE/WiFi coexistence FBAR filters for mobile and wireless.
The MGA-43003, MGA-43013, MGA-43024 and MGA-43040 Pas are priced at $9.24 USD each in 1,000 unit quantity. Samples and production quantities are available now. More information at the company website.
Noise eXtended Technologies (Noise XT) introduced the 2 MHz to 7 GHz SLC Ultra-low Jitter/Dual Clock Synthesizer. The SLC is a single or dual clock USB synthesizer designed for cost-sensitive applications. Noise XT claims that this product has the lowest phase noise of any synthesizer in a compact, low cost package. (The SLC measures 85 x 110 x 200 mm.)
The SLC offers two clocks in a single package and, for example, achieves jitter measurements to -170 dBc/Hz at 10 MHz and 40 fs (femtoseconds) RMS on a 155 MHz clock.
