Ted Rappaport, founding director of NYU WIRELESS and a leading proponent of using the millimeter wave spectrum for wireless communications, discusses the FCC's recent rulemaking actions and technology developments that are paving the way to 5G.
RFMW Ltd. announces design and sales support for Peregrine Semiconductor’s PE42421, a low cost, high performance SPDT switch. The PE42421 operates from 10 MHz to 3 GHz with insertion loss as low as 0.35 dB and isolation as high as 30 dB between ports. The input 1 dB compression point is dependent on voltage and as high as 33.5 dBm. Input IP3 is 55 dBm. Peregrine’s PE42421 low cost switch finds applications in RFID, home networking, small cells and WiFi.
RFMW Ltd. announces design and sales support for broadband, omni-directional whip antenna from Southwest Antennas. The model 1000-029 covers the frequency band of 225 to 512 MHz for broadband radio applications where rugged antenna options are required. The Southwest Antennas’ 1000-029 is fully potted and waterproof to 20 meters when installed, yet is lightweight (1.9 oz) and highly flexible. The TNC male connector is black chrome plated and the antenna is black polyolefin.
MCV GPS, GlobalStar, Glonass ceramic patch antennas offer precision and high gain along with a wide band PIFA chip antenna covering 698 to 960 MHz and 1700 to 2700 MHz for 3G/4G applications. MCV VHF/UHF and LTE MIMO DAS antennas are ideal for base station and indoor/outdoor repeater. Meta-material antenna can effectively isolate Wi-Fi frequency from LTE bands.
RFMW Ltd. announces design and sales support for a GaN power amplifier. The Qorvo QPA2237 offers 10 W of saturated output power from 30 MHz to 2.5 GHz. Small signal gain is >18.5 dB while large signal gain is >13 dB. The QPA2237 draws 360 mA from a 32 V supply with 48% power added efficiency (PAE). Serving electronic warfare (EW), radar and communications markets, the QPA2237 comes in a 4 x 4 mm, plastic overmold QFN package.
Skyworks introduced two RF switches ideal for the Internet of Things applications including the connected home. The SKY13587-378LF, which is a pHEMT GaAs SPDT switch, can be used for transmit and receive switching in industrial, lighting and smart energy applications, as well as 802.11a/b/g/n WLAN networks. The SKY13588-460LF is a CMOS silicon-on-insulator SP3T switch made for antenna selection in Wi-Fi applications in IoT systems.
Exodus introduces the AMP1071, a solid-state RF amplifier module covering the entire ultra-wide 2.0 to 20.0 GHz frequency range instantaneously at 20 W CW minimum. Using State of the Art GaN devices, the AMP1071 operates from a 32 VDC source at less than 10 A consumption. This module is suitable for use with all single channel modulation standards and applications requiring high power and ultra-wide band coverage.
RFMW Ltd. announces design and sales support for a small cell duplexer. The Qorvo TQQ6103 BAW technology offers high isolation for LTE Band 3 uplink (1747.5 MHz) and down link (1842.5 MHz) filter requirements in base stations, repeaters, signal boosters and small cells. With full 75 MHz bandwidth, in band insertion loss is only 4.1 dB while UL/DL attenuation is 44 dB. The TQQ6103 requires no external matching and handles 29 dBm of power.
RFMW Ltd. announces design and sales support for high gain, high linearity power amplifiers designed for ‘small cell’ applications. The Skyworks SKY66186-11 provides 38 dB of gain for LTE radios operating in the 728 to 768 MHz frequency range (B12, B13, B14, B17). Designed for high linearity at elevated temperatures, the SKY66186-11 supports outdoor applications where ambient temperatures range from -40 to +85 degrees C.
Richardson RFPD Inc. announced the availability and full design support capabilities for a passive switch from MACOM Technology Solutions Inc. The MADP-011048 uses silicon PIN diodes in a non-magnetic surface mount package. There are two sets of diode pairs, constructed in an electrically-isolated, anti-parallel configuration, that operate from 5 to 400 MHz. MADP-011048 is well suited for MRI passive switching applications.
MECA introduces a family of 1, 2 and 5 W, 7/16 DIN-male and female coaxial weatherproof (IP66) loads for indoor or outdoor deployments. Their rugged construction and excellent performance (VSWR 1.15:1 Typical) across all wireless bands from Hz to 3 GHz makes them ideal for base station and RF/Microwave lab applications.
