    I coordinate a design team for the realization of a device that includes an RF section but in the group we have limited knowledge of RF design. In particular I need to make a Class E RF amplifier with the following characteristics: • operating frequency 406.0 MHz • power 5W (37dBm) • TX duty cycle 10ms (transmission time 500 ms every 50 s) • 7.2Vdc power supply • input power 100mW (20dBm) • two-phase modulated input signal • input impedance 50Ω • output impedance 50Ω • efficiency ≥ 70% • operating temperature between -20 and +55 • the output power must go from 10% to 90% of the max power in less than 5ms • must work with VSWR between 1: 1 and 3: 1 • must not be damaged if the load is short...

Explore the differential amplifier characteristics of gain and impedance in both differential and common mode, and the common mode rejection ratio (CMRR), then add current source biasing and an active load. You will then add an output stage to make the two-stage op amp. The final step will be to add an improvement of your choice. For maximum CMRR, the differential pair transistors should be as identical as possible. Instead of discrete transistors, we will use the MPQ3904 array, which has four npn transistors on one chip. Later, for the active load you will also need two matched...

Preferably a noise cancelation circuit for the mic inputs . The board should work at a wide power supply source that can variate from 8-10v all the way to 30V dc. I am minded for the ICs for the amp and the Correction but open to suggestions as the output amp should be protected to shorts to low /high . Output power minimum 25w .

    Trophy icon Design a Rock’n Roll suitcase Udløbet left

    This project is to design a suitcase or a briefcase that immediately reminds you of those beautiful vintage guitar amps. The case should use the form language of vintage guitar amps. It actually CAN look like a true guitar amplifier, but it doesn’t have to. Your solution can as well just reflect the design ideas that are typical for this kind of devices. The challenge is to use those typical elements without overloading the case. The proportions of the case can be anywhere between a rather slim briefcase (for your next meeting) and a more „bulky“ suitcase (for your dancing shoes, beer cans or whatever). If you find a design solution that can be used for anything between briefcase and suitcase - so much the better. The pictures show our prot...

Many also have a WiFi network or other proprietary network to provide access to data from monitoring instrumentation (geotechnical, hydrological, gas detection/air quality etc.), vehicle/equipment and personnel tracking systems, etc. Mostly, these two systems operate independently, leading to a significant amount of infrastructural duplication.
