analog amplifier with transistors, this should be designed in proteus

I am in need of a custom RF meter (100Mhz - 90 Ghz. , 20.000 sampling rate per second). Therefor looking for an electrical engineer. I am needing to build an RF meter that can outperform an ENV RD-10. RD-10 specs: RF Frequency range 100MHz to 8GHz RF measuring range -60dBm to +5dBm RF Typical accuracy ±6 dB I am in need of a meter that can go beyond 8Ghz. Preferably 100Mhz - 90 Ghz. The issue at hand. ''Professional equipment'', like Narda for example, for political reasons; work with a low sampling rate (mostly 5/second sampling rate). I am in need of a high sampling rate (20.000/second sampling rate). Price is open for discussion.

I am looking for a skilled PCB designer who can create a board that measures between 2-4 inches and contains multiple components and layers. The board will primarily use surface-mount components. The project requires moderate complexity and the ideal candidate will have experience with designing boards with multiple layers and components. Expertise in PCB layout and design software is a must. Attention to detail and the ability to meet tight deadlines are also essential.

I am in need of an experienced circuit board designer to create a circuit board from a hand drawn schematic. The purpose of the board is to convert a 25VAC analog pulse signal to a digital input that can be read by a Raspberry Pi. I am open to suggestions for the size and form factor of the board, as well as the budget for any components required. The designer should have extensive knowledge in circuit board design and preferably experience with components suitable for use in a Raspberry Pi environment. Would like to use PiHat design allowing me to connect directly onto GPIO of Raspberry PI. Have a picture of the circuit design and the final board. I live in Syracuse NY USA would prefer a local resource but not a requirement

I am working with a leading producer to take guitar effects and put them back into rack gear. We are emulating the tube screamer circuit and have other requirements for the circuit to give it a unique edge. It is at POV stage so budget it tight! I need help to design and build to a level that is in line with safety standards to not have limitations in global markets like the US or Europe. I can supply more detail once I have gauged the suitability of the project.,

I want a simulation of two CMOS level circuits: full subtractor and 1-bit comparator, with their outputs. attached are the two circuits we need in CMOS level using ltspice. we can agree on price.

I need someone to assist me to design Pcb (schematic) that could run Linux Pcb Bootloader ….

I am looking for a skilled freelancer who can help me with my PCB and schematic designs(4 different design) review and completion. The current state of the design is complete, but it needs a thorough review before finalization. Ideal Skills and Experience: - Experience in PCB design and review - Knowledge of EasyEda PCB design software (All the files are designed in EasyEda ) - Experience/Knowledge with ESP32-S3 Chip/module - The deadline for completing the review and completion is less than a week, so I need someone who can work efficiently and deliver high-quality work within a tight timeframe. Don't apply if you don't know about the EN pin and the reset/ programing mechanism of the esp32-s3 chipset/module as the reset and programming mechanism needs to be verified to fin...

Hello i am working on custom battery pack . I have designed the pcb for the pcb using the texas ic BQ76920. I am looking someone to check the circuit diagram/schematic and the pcb parts and find any mistakes cause currently is not working properly. Specifically i have wrong current readings. Also in my last test i damaged the ic.

Hello there, I need to design an RF jammer as a school project, need some help and explenation on it. Thinking of using small design and jam a remote control or wifi signals.

We need you to take our 12v circuit design and turn it into a PCB design with terminal block inputs and outputs. Currently we use 3rd party bi-stable latching relays that have a SET, RESET and REVERSE input however we would like to incorporate this into the PCB design so we don't need third party controls if possible. Below is the links to the special components, you can use any DPDT relays. Timer BiStable Latching Relays Also the circuit needs to be optimized and could possibly be simplified with the introduction of diodes and removal of some relays. The outcome needs to be a print ready circuit board design that is compact, optimized and function for our needs as described in the attached sketch.

I am looking for a freelancer who can help me develop a 3 Phase Sequence Monitor for my system. The ideal candidate should have experience in electrical engineering and be familiar with microcontrollers and relay control systems. A low cost Microchip microcontroler shall be used. The power for the microcotroller, relay and interface circuit should be obtained from the 3 phase mains with a linear impedance converter (i.e. not switching.) Function description: After 3phase mains is applied, the circuit should start the detection. The power led should indicate that the microcontroller is working and performing the sequence detection. The output relay and the "Phase Ok" led should be synchronized ( using the same microcontroller pin is Ok.) Scope: Provide firmware, Altium proj...
