UHF to mmWave Cavity Filter Solutions
Cavity filters achieve much higher Q, steeper rejection skirts, and higher power handling than other filter technologies, such as ceramic resonator filters, and are utilized where low passband insertion loss and high rejection of neighboring channels/spurious emissions are critical.
Frequency Modulation Fundamentals
The development of crystal-clear FM communications was an innovation of genius and toil. Utilized today in applications such as radar, seismology, telemetry and two-way radios, FM remains a ubiquitous real world technology because of its superior signal to noise ratio compared to other modulation schemes. Read on to learn about the history, theory and illustrative use cases including FM radio and the radar altimeter.
44 GHz Programmable Signal Generator
The Mini-Circuits’ SSG-44G-RC is a 0.1 to 44 GHz signal source with an RF output range of -40 to +17 dBm with fine resolution. This model supports CW and pulsed (≥ 0.5 μs) outputs while sweeping and hopping between power levels and frequencies.
50W SSPA with Built-In Signal Source & Control
The RFS-2G42G5050X+ takes Mini-Circuits’ robust line of solid state, connectorized, high-power amplifiers for RF energy to a new level by integrating the versatility of a signal generator with a 50W amplifier. The ruggedness of the RFS-2G42G5050X+ is enhanced by the built-in monitor and control circuitry which protects the module from excess temperature, current, supply voltage, forward and reverse power.
The Basics of Orthogonal Frequency-Division Multiplexing (OFDM)
While traditional Frequency Division Multiplexing has been around for over 100 years, OFDM was first introduced by Robert W. Chang of Bell Laboratories in 1966.1,2,3,4 In OFDM, the stream of information is split between many closely-spaced, narrowband subcarriers instead of being relegated to a single wideband channel frequency.
Mesh Network Simulators Up To 16 Ports
Mini-Circuits has expanded our range of test systems for characterizing wireless mesh network devices, now with standard configurations up to 16-ports built to order with fast turnaround. All external ports of the mesh are interconnected to simulate an over-the-air wireless mesh configuration.
High Pass Filters – Compact, Cost-Effective and Extending to 60 GHz
When designing mmWave frequency systems that span Q-band and half of V-band, engineers are often faced with difficult tradeoffs when it comes to filter selection. Mini-Circuits has broken through with our HFCQ (1008), HFCN (1206) and HFCV (1210) series high pass filters. These latest LTCC filters from Mini-Circuits exhibit passbands that cover Q-band and the lower half of V-band while offering a combination of insertion loss, return loss, rejection, size, cost, repeatability, ruggedness and reliability that has only now become available.
MMIC Package Customization
See how Mini-Circuits helped a customer replace an EOL (end-of-life) part by repackaging one of our existing MMIC amplifier die into a form-fit-function compatible solution for the customer's board layout.
TTL-Controlled Solid State Switches
Mini-Circuits has expanded its lineup of switching solutions for test applications with new 4-way and 8-way TTL-controlled solid-state switches.
K-Ka Band Variable Gain Amplifier with Monitor & Control
Mini-Circuits' new ZVA-18443VG+ wideband, variable-gain amplifier operates from just a single +10 to +15V supply while providing 47 dB gain and +31 dBm of RF output power. The amplifier provides 17 dB of calibrated gain range via analog or digital (TTL) control as well as a full suite of telemetry features for output power, temperature and fault tracking, all accessible through a user-friendly GUI.
2W MMIC Amplifier Covers 0.01 to 10 GHz
Mini-Circuits is pleased to introduce the PMA5-83-2W+ GaAs MMIC power amplifier capable of delivering 2W PSAT with an operating bandwidth from 0.01 to 10 GHz. Combined with a gain of 12 dB, this amplifier exhibits a low NF of 3.5 dB and high linearity (P1dB = +31 dBm and IP3 = +43.5 dBm).
MIMO Systems
This article explores the origins of MIMO technology and explain how concepts of polarization diversity and spatial diversity enable these systems to scale capacity for higher data rates and multiple simultaneous connections to user equipment. Use of MIMO in LTE-Advanced (LTE-A) communications and Wi-Fi 6/6E are then described by way of example.
