RFMW, Ltd. announces design and sales support for a discrete 800-Micron GaAs pHEMT FET. The TGF2080 from TriQuint Semiconductor is constructed without via holes thereby allowing for self-biasing and eliminating the need for a negative supply voltage. Available in a 0.41 x 0.54 x 0.10mm chip suitable for eutectic die attach, the TGF2080 was designed using TriQuint’s proven 0.25um pHEMT process which optimizes power and efficiency at high drain bias operating conditions. The TriQuint TGF2080 provides 29.5dBm P1dB with 11.5dB associated gain and power added efficiency (PAE) of 56%. A silicon nitride, protective overcoat layer provides a level of environmental…

RFMW, Ltd. announces design and sales support for the MiniRF, 4-way splitter, model MRFSP0012. Covering the common CATV bandwidth of 5 to 1002MHz, the MRFSP0012 replaces three, 2-way splitters commonly used to achieve a 1 to 4 split thus saving board space, reducing part count and offering easier design configuration. And, the MiniRF MRFSP0012 offers a cost savings over comparable performing, multi-splitter topologies. Mid-band insertion loss is typically 0.75dB with 25dB isolation. Amplitude balance is typically <0.1 dB while phase balance is typically <1 degree with a maximum of 2.0 degrees. A 75 ohm characteristic impedance makes the MiniRF MRFSP0012 ideal for broadband, CATV applications. The MRFSP0012 comes on a castellated,…

RFMW, Ltd. announces design and sales support for Skyworks diode products. The SMV1771-040LF is a surface mount, hyperabrupt, tuning varactor diode offering a high capacitance ratio and low series resistance. This combination of characteristics makes the Skyworks  SMV1771-040LF ideal for use in low phase noise, voltage controlled oscillators (VCOs) operating from VHF to 2.5GHz. Applications include telecom infrastructure, military, automotive and consumer. The Skyworks SMV1771-040LF provides a replacement for the Renesas HVC374B which has announced end of life status.

RFMW, Ltd. announces a web based tool that allows designers to create semi-custom Voltage Controlled Oscillators (VCOs) and Phase Locked Loop (PLL) synthesizers. Designers can search a large database of existing products based on parametric requirements and jump directly to existing product information. Should the database not include an exact match, users can define their requirement for an RFMD factory review and feedback. Often, requirements are a simple derivative of existing products. Narrow-band to octave band frequency coverage from product families ranging 10MHz to 8.5GHz. Ultra low phase noise oscillators provide unsurpassed performance in standard and small form factor, surface…

RFMW, Ltd. announces design and sales support for a discrete 600-Micron GaAs pHEMT FET. The  TGF2060 from TriQuint Semiconductor is constructed without via holes thereby allowing for self-biasing and eliminating the need for a negative supply voltage. Available in a 0.41 x 0.34 x 0.10mm chip suitable for eutectic die attach, the  TGF2060 was designed using TriQuint’s proven 0.25um pHEMT process which optimizes power and efficiency at high drain bias operating conditions. The TriQuint  TGF2060 provides 28dBm P1dB with 12dB associated gain and power added efficiency (PAE) of 55%. A silicon nitride, protective overcoat layer provides a level of environmental…

RFMW, Ltd. announces design and sales support for TriQuint Semiconductor TGF2040, a discrete 400-Micron GaAs pHEMT FET. Designed using TriQuint’s proven 0.25um pHEMT process, power and efficiency at high drain bias operating conditions are optimized. The TriQuint TGF2040 supports circuit designs to 20GHz with up to 26dBm P1dB, gain up to 13dB and 55% power-added efficiency (PAE). The TGF2040 is constructed without via holes thereby allowing for self-biasing and eliminating the need for a negative supply voltage. Power supply requirements are reduced which is particularly useful in airborne applications such as UAVs. Along with hi-rel defense and aerospace, additional applications…

RFMW, Ltd. announces design and sales support for TriQuint Semiconductor dual device amplifier model TQP3M9041. Spanning the frequency range of 2.4GHz to 4GHz, this high linearity, ultra low noise figure LNA offers a 0.8dB noise figure in a balanced configuration at 1.95GHz. Input IP3 is 20dBm with associated gain of greater than 18dB. The TriQuint TQP3M9041 operates from a 4.4V positive supply with no requirement for a negative gate voltage. A shut down mode allows the device to idle at reduced current in TDD type systems. Designed using dual, matched-pair E-pHEMT devices, noise figure from a single channel is 0.33dB…

4/24/2013 – San Jose, California: RFMW Ltd. and RF Circulator Isolator, Inc. (RFCI) today announced a worldwide distribution agreement effective April 3, 2013. RFCI acquired the Circulator and Isolator product line from RFMD upon RFMD’s exit of the business. RFMW Ltd. is a specialized distributor providing customers and suppliers with focused distribution of RF and microwave components as well as specialized component-engineering support. According to the agreement, RFMW will distribute RFCI’s broad portfolio of ferrite products including surface mount and coaxial circulators and isolators as well as customer specific devices to satisfy diverse requirements.

RFMW Ltd., announces design and sales support for a new line of microwave absorbing materials from MAST Technologies. These “Tuned Frequency” absorbers are electrically optimized for specific applications and intended for customers who experience high frequency cavity resonance effects or high frequency EMI emissions above 18GHz. Proper application of the absorber eliminates these unwanted signals. This durable elastomeric material is flexible and will not crack, even in outdoor environments. Halogen free and RoHS compliant, the material is electrically non-conductive and can be placed in direct contact with electronic circuits. MAST model number MR11-0034-00 is tuned for absorption at 35GHz. The…
