RFMW, Ltd. announces design and sales support for omni-directional concealment antenna products specifically for use in covert surveillance or other applications where an antenna needs to be hidden from view or disguised to not draw attention. Southwest Antennas’ model 1066-014 offers quad-band, 4G, LTE cellular coverage for global use. This antenna offers superior, 360 degree horizontal beamwidth and 76 degree low-band vertical beamwidth (46 degree high-band vertical beamwidth) when properly mounted. Pre-assembled with a 12 inch RG-316 cable, gain is 2.2dB in either low-band (698 to 960MHz) or high-band (1710 to 3000MHz). When used with a radio having multiple antenna…

RFMW, Ltd. announces design and sales support for a broadband, high-isolation switch from Qorvo. Absorptive by design, the QPC6014 can handle up to 4 watts of input power from 50 to 6000MHz and 2 watts from 5 to 50MHz. Offered as a single-pole, single-throw (SPST), isolation ranges from 70dB at lower frequencies to 43 dB at 4GHz. The QPC6014 simplifies designs as it needs no DC blocking caps and is offered in a 2x2mm QFN package. Input IP3 is 58dBm.
RFMW, Ltd. announces design and sales support for a series of high power amplifiers from Skyworks Solutions. The SKY6629x-11 series includes eight models of high-efficiency (approx. 35% @ Pout = +28dBm), 4W amplifiers covering frequency bands from 700 to 3800MHz. Targeted for the fast growing enterprise small cell market, these 4-watt PAs meet higher data rate and lower power consumption requirements for indoor and outdoor enterprise systems, support the majority of the world’s most popular bands, and can be used in FDD and TDD 4G LTE, 4.5G and 5G systems, as well as the recently launched Citizen’s Broadband Radio Service…
RFMW offers a Qorvo white paper outlining methods for proper handling, component placement, optimum attachment methods, and interconnect techniques for use with GaN and GaAs microwave monolithic integrated circuits (MMICs) in electronic assemblies.
RFMW offers a white paper from Southwest Antennas providing the basics of understanding MIMO communication. Multiple-In, Multiple-Out, MIMO communication sends the same data as several signals simultaneously through multiple antennas, while still utilizing a single radio channel. Related topics outlined in this paper, Understanding the Basics of MIMO Communication Technology, can be understood by readers of all technical levels, particularly those that are new to the RF market or have no previous working experience with MIMO technology.
RFMW, Ltd. announces design and sales support for an expanded offering of SMD square air coils from Frontier Electronics. The new LSQ1111A – LSQ2929A series offer a higher current rating (up to 5.7A), an inductance range of 27nH to 500nH and SRF values as high as 2.6GHz . Designed primarily for use in RF circuits such as filters, bypassing and/or decoupling signals, these larger coils compliment the already established LSQ0706A – LSQ0908A series. Square air coils offer advantages over their round coil counterparts such as: higher inductance values for a given LxWxH, higher self-resonant frequencies, lower coil capacitance, and pick…
MiniRF has released a new Product Selector Guide to aid RF passive component selection for existing and emerging Broadband/CATV and Wireless Communications Systems. These surface mount components include transformers, couplers, splitters, and chokes with 50 and 75 ohm options. Wire wound designs offer high performance at economical prices.
RFMW, Ltd. announces design and sales support for the Skyworks Solutions SKY66105-11 Front End Module (FEM). The SKY66105-11 offers high output power (30dBm) for 902 to 931MHz, ISM band transmit applications such as smart metering for water, gas and electric. With integrated harmonic filters and a DPDT switch for diversity antennas, this FEM also incorporates on-board matching and integrated shielding thereby reducing required board space and easing design. Supply operation is flexible from 2.0 to 4.8V. Turn-on/turn-off time is 1-2 micro seconds. This Skyworks FEM is housed in a 8x6mm module with exposed ground paddle and surrounding shielding.
RFMW, Ltd. announces design and sales support for a 1900W pulsed RF power transistor from Ampleon. The BLF189XRB supports industrial applications in the 30 to 150MHz frequency range such as Magnetic Resonance Imaging (MRI). Offering gain of 23dB, efficiency is 63%. Excellent ruggedness is a hall mark of Ampleon high power LDMOS and the BLF189XRB can withstand VSWR mismatch as high as 65:1. Excellent thermal stability is enhanced by the flanged, balanced ceramic packaging.
RFMW, Ltd. announces design and sales support for a 10MHz to 6GHz RF power limiter capable of handling 100 watts of pulsed input power. Peregrine Semiconductor’s PE45361 is a monolithic structure 8 times smaller than discrete, PIN-diode solutions and eliminates thermal hysteresis. The adjustable input 1dB compression point (limiting threshold) is set from +7 to +13dBm via a low current control voltage (VCTRL), eliminating the need for external bias components such as DC blocking capacitors, RF choke inductors and bias resistors. Fast response time of <1ns ensures instantaneous protection of sensitive components and rapid return to normal operation. Highly flexible…
