      Over on GitHub Ian Wraith has released his design and microcontroller code for a low cost GHz downconverter circuit. A downconverter is a hardware device that shifts the signals that it receives into a lower frequency band. This is useful in the case of RTL-SDRs and Airspy SDRs, as their maximum frequency range is only GHz. Ian's GHz downconverter reduces those GHz .   The amplifier is built around Mini-Circuits PSA+ E-PHEMT Ultra Low noise MMIC amplifier operating from 50 MHz to 4 GHz. Small SOT package combine low noise and high IP3 performance with internal match to 50 ohms. Manufacturer declare a dB NF @ 1 GHz and dB NF @ 2 GHz with IP3 value reaching dBm.

    ® Series amps feature five 12AX7 preamp tubes and four 6L6GC power amp tubes, with presence and resonance controls and three-band EQ for taming their notorious tone. The Series is the undisputed go-to guitar amp series for scores of rock and metal bands due to their raw tone, relentless power and road-proven reliability.

    A Simple Harmonic Mixer/Antenna Feed for 47 and 76 GHz Experiments K. Banke - N6IZW - San Diego Microwave Group Just in the last year, members of the SDMG have started experimenting at 47 and 76 GHz. The issues for those bands seemed to be providing a clean LO signal and coming up with a harmonic mixer and antenna with feed. Mixers are used in up-conversion and down-conversion circuitry of wireless systems. Fundamental operation of mixing phenomena is described and figures of merits for mixers are defined. Section , Planar Antennas, presents a unique and practical class of antennas for application at microwave- and millimeter-wave frequencies. These antennas.

Cheap Mixer with Good Preamps I need a mixing board. my tape machine only has four tracks and my digital interface has only two, so I would like to invest in a mixer with good preamps and at least 6 xlr ins (hoping for more like 8, will settle for 4 if price is a steal and preamps are excellent) so I can use the main L/R outs to record with.

It's a great time to upgrade your home music studio gear with the largest selection at Fast & Free shipping on many items. Im looking at getting a cheap mic preamp if it will upgrade my sound, or should i stick with the mixer, If so is the Mackie VLZ Pro preamps alittle better then the Yamahas, I just want to do the most logical thing until i can drop $ on a mic preamp P.S i only use the mixer to bring mic level to line level, So basically my.

Rather than dealing with separate preamp, EQ, and dynamics control units, many engineers prefer the convenience of channel strips that combine two or all three of these functions into one unit.

From vintage-flavored tubes to state-of-the-art solid-state, no matter what kind of sound you're into, Sweetwater can make your sonic vision a reality. In the most basic terms, the audio mixer, or mixing console as it’s sometimes called, combines audio signals, processes them, then routes them to wherever they need to ys, many different devices offer some mixing capabilities.

Even tablets and smart phones teamed with the right apps and interfaces can perform some mixing functions. An audio mixer, also called a mixing console, is an electronic device for combining, and modifying audio modified audio signals are summed to produce some combined output signals.

Audio mixers can be analog or digital type. Digital mixing consoles use Digital Signal Processing concepts and analog mixers are usually based on op-amps electronic circuits/5(8). The feedback capacitor C fb is usually constructed in the vicinity of the input FET by bringing a wire near the FET gate.

Feedback capacitance of about pF is typically obtained in this way. In the PLF preamplifier the leakage current charges the input capacitance (essentially C fb), and the output follows a constant ramp as shown in Fig. a predetermined value set by the Schmitt. Mixing a signal with a tone is the core concept behind devices like upconverters, downconverters and tuners.

For example, by generating a mixing tone at 2 GHz with the moRFeus, we are able to view GHz WiFi signals at GHz - 2 GHz = MHz. In the screenshot below we set moRFeus to run in mixer mode with the LO frequency set at 2 GHz.

In sound recording and reproduction, and sound reinforcement systems, a mixing console is an electronic device for combining sounds of many different audio signals. Inputs to the console include microphones being used by singers and for picking up acoustic instruments, signals from electric or electronic instruments, or recorded music.

Depending on the type, a mixer is able to control analog. A preamplifier (preamp or "pre") is an electronic amplifier that converts a weak electrical signal into an output signal strong enough to be noise-tolerant and strong enough for further processing, or for sending to a power amplifier and a t this, the final signal would be noisy or distorted.

They are typically used to amplify signals from analog sensors such as microphones.
