Both devices utilize Skyworks TC-SAW filtering for temperature compensation, providing dependable performance in applications such as wearables, action cameras, drones, asset trackers and personal navigation devices. Extremely low leakage current of 1uA extends battery life. The SKY65933-11 runs from a single DC supply voltage of 1.5 to…
RFMW, Ltd. announces design and sales support for a broad bandwidth, GaN, solid state power amplifier from Aethercomm. Model number SSPA 6.0-12.0-100 operates from 6 to 12GHz and delivers a minimum output power of 100 Watts. Employed in high shock and vibration environments, the SSPA 6.0-12.0-100 can be used on board many different types of airborne platforms. Typical small signal gain is 53-55dB. Operating from a +28V supply, this amplifier includes an external DC blanking command that enables and disables the module in less than 10 uSec. Offered in a modular housing that is approximately 5”(width) by 9”(long) by 2”(height).
RFMW, Ltd. announces design and sales support for a high performance LNA covering 7 to 14GHz. The Qorvo QPA2609 provides 26dB of small signal gain with a noise figure of 1.1dB for point-to-point and satellite communication systems. Packaged in a small, 4 x 4 mm plastic QFN, the QPA2609 is matched to 50 ohms with integrated DC blocking caps on both I/O ports for easy handling and simple system integration. OIP3 is 25dBm. P1dB is 18dBm. Biased with 3.5V, this GaAs device draws 120mA of current.
RFMW, Ltd. announces design and sales support for a Southwest Antennas’ helical designed, bifilar antenna. The 1032-034 is a Right Hand Circularly Polarized (RHCP) omnidirectional antenna operating from 4.4 to 5.9GHz with 3.75dBic of gain. Bifilar antennas minimize mismatch between ground stations and aircraft as they bank and turn. Circular polarization reduces atmospheric disruption. The 1032-034 eliminates the “key hole” gap seen in dipole antenna radiation patterns to provide continuous overhead coverage thereby supporting close in communication with vehicles such as airplanes, helicopters, and UAVs. A sealed spring base makes it safe for vibrating platforms and reduces the risk of…
RFMW, Ltd. announces design and sales support for a phase-frequency detector from Microsemi. Incorporating dual, 0.01 to 40GHz, 7-bit programmable, high-speed prescalers for reference and VCO inputs, the PFD1K is ideally suited to phase locked loop applications from DC to 8GHz. The prescalers are 1 to 127, integer dividers that feed the differential input of the phase-frequency detector. Dual charge pumps follow the phase-frequency detector and offer differential outputs. Single Sideband phase noise is -153dBc/Hz @ 10KHz offset. The PFD1K operates with a single positive or negative 3.3V supply, and is packaged in a 40-pin, 6mm x 6mm ceramic leadless…
