RFMW announces design and sales support for a dual path amplifier from Qorvo. The QPD0011 is an asymmetric, dual-path, discrete GaN on SiC HEMT in a DFN package operating from 3.4 to 3.6 GHz. With 15 dB of gain, this device can deliver an average power of 15 W in a Doherty configuration or a Psat of 50 dBm at 3.5 GHz. Operating from a 48V bias, the QPD0011 has applications in 5G massive MIMO, microcell and small cell base stations.
RFMW announces design and sales support for Smiths Interconnect TSX Series chip attenuators with extended frequency range. The TSX series chip attenuators span DC to 50 GHz with 1 to 3 Watts of input power handling capability based on individual device attenuation values as follows: 0-1 dB attenuators are rated at 3 W, 2-3 dB rated at 2 W, 4-20 dB rated at 1 W. Q-band performance addresses new markets and applications including instrumentation, radar, satellite and 5G systems. In transmitters, low VSWR increases output power potential while the small, 0604 package size, ideal for pick and place manufacturing, reduces…
RFMW announces design and sales support for a versatile, SiGe driver amplifier from NXP. The BTS6201U amplifier delivers high linearity with 27 dBm typical P1dB output power in its frequency range of 2300 to 4200 MHz. A dual-stage, single-ended design provides 31 dB of gain and is matched to 50 Ohms with integrated bias control, supporting fast switching for TDD systems. Class AB drain efficiency is 20% and signal bandwidth (IBW) is 200 MHz from this 5 V device. Typical applications are high-linearity pre-drivers in cellular infrastructures, such as bands B40, n41, B42, n77, n78 and C-band. Offered in a…
Radar receivers require low noise front ends to be able to detect targets at a long range. Simultaneously, they are frequently operated in an environment where a very high-power transmitter (a radar transmitter) will periodically leak into the receiver path, potentially damaging the receiver. A classic example of this is when a plane flies past a high-power radar transmitter, leading to damaging radiation levels for the plane’s receiver. This damage can be prevented by using a limiter. Figure 1: High power transmitters can damage high-sensitivity receivers An ideal RF limiter is a device that passes RF signals below a certain…
RFMW announces design and sales support for a CATV step attenuator for Qorvo. The QPC4614 is a 75Ω, 6-bit, digital step attenuator (DSA) that features high linearity over the entire 31.5 dB gain control range in 0.5 dB steps. Spanning 5 to 2000 MHz, at 1000 MHz, insertion loss is only of 1.2 dB and IIP3 is 65 dBm. The QPC4614 features three modes of control: serial, latched parallel, and direct parallel programming. Patented circuit architecture provides overshoot-free transient switching performance. Offered in a 20-pin 4.0 x 4.0 mm QFN package.
RFMW announces design and sales support for a Southwest Antennas’ dual-band antenna. The 1055-404 is directional MIMO sector antenna for use with 2 or 3 port radio systems. The antenna has three, N-Type female RF ports, each feeding its own discrete antenna element, with 2 elements operating at 1.7 to 2.5 GHz, and the third port operating at 1.35 to 1.9 GHz in the following configuration: 1 slant right (1.7 to 2.5 GHz) 1 vertical (1.35 to 1.9 GHz) 1 slant left (1.7 to 2.5 GHz) Slant and vertical polarization offer polarization diversity, preventing interference when multiple streams are used.…
RFMW announces design and sales support for high frequency power limiters from Marki Microwave. Ideal for protecting sensitive components and for applications requiring high linearity, Marki’s HLM-40PSM, GaAs, Schottky diode, signal limiter provides 11 to 19 dBm flat leakage with low insertion loss and low return loss from DC through Ka band. Typical 1 dB compression point is 14 dBm. Power handling is 9.5 Watts peak or 2.5 Watts CW. Also available as wire bondable die or a connectorized module.
RFMW announces design and sales support for multi-throw switch Qorvo. The Qorvo CMD235 is a broadband MMIC SP5T switch in die form covering DC to 18 GHz with low insertion loss of 2.2 dB and high isolation of 30 to 50 dB (depending on port) at 10 GHz. The switch also includes an on board binary decoder circuit which reduces the number of required logic control lines from five to three. The CMD235 operates using voltage control logic lines of 0/-5 V and consumes minimal DC current for multiplexing, signal routing, signal termination and antenna arrays.
