Radio/microwave Frequency + Software Defined Radio Software Consultation. -- 2

I need an RF Filter design for 9GHz to 10GHz. The design must comply with the following parameters : 1. Sma connector at input and output. 2. Insertion loss : 3db max 3. Stop band rejection : 40-30db The deliverables will be as following : 1. Simulated S parameters 2. Gerber files for fabrication. 3. Design files Please don't bid if you don't have rf design experience.

Busco desarrolladores e integradores que cuenten experiencia con el uso de antenas RFID y etiquetas UHF para un proyecto de almacenamiento de información mediante RFID.

Looking for someone that knows and understands the practical knowledge of a Microwave Transmitter and components. Be ready to design a real life system and design the circuit of it. Please only bid on project if you understand this very well.

Im working on a project and need a passive RFID Tag for ID cards, and need advice to find the best tag for the rough conditions of the usage.

The goal is to efficiently characterize sheet absorber material to quantify the transmission loss per mm thickness and the reflectance of the material.

I need a PCB designer for my RFID projects. If you have BLE and RFID antenna experience it's a big plus.

Buscamos que se realice el siguiente proyecto: - Desarrollar un sistema que tenga 3 antenas de lectura de RFID de corta distancia, para triangular la posición. - Estas 3 antenas triangularan la posición de una etiqueta RFID de forma precisa. - La distancia de lectura será de 20 cm, y la precisión de posición alta. - Desarrollar una electrónica general de control que lea las 3 antenas y de una señal de salida digital cuando se cumpla un requisito. ------…

Hi Our company manufactures products for the agricultural sector for the Irish, UK and European markets One of the products that we currently produce is an animal welfare product known as an “Automatic Calf Feeder” which as the name suggests automatically mixes powdered milk with water and feeds it to calves The machine comprises a main control unit where the mix is made and pumped to remote drinking stalls which are located in the calf pins throughout the shed where…

Looking to read a tire pressure monitoring sensor that emits a 440mhz signal using Arduino. I have all the hardware but am having trouble receiving signals from the sensor.

I need to find out if there are any federal laws in the United States against importing/exporting a radiocommunications device with or without a license. It would likely be an obscure old law. Any law anywhere close would be good to know.

Hi, looking for anyone I can consult with who has experience with radiofrequency, SDR software. Thanks
