I want to make a simple rectifier for an RF signal, frequency less than 10 MHz. The schematic below (view with fixed font) is from an article describing a circuit useable with much higher frequencies and used a hot-carrier diode (1N5711). For relative low frequencies would a general purpose diode such as a 1N4148 be adequate?
If a hot-carrier would be necessary I have a problem because I don't have any but I do have a few high speed transistors: BSV52, BSF17, J310. Would the base-emitter or base-collector junction of one of these transistors be a suitable substitute for a hot-carrier diode?
