Re: SIMPLE FM RECEIVER
I have attached the datasheet of TDA7000 (Philips) wich is one of the "simplest" IC FM radio receiver. It needs only a few external components. A PCB "sugestion" is also given...
Re: AM simulations
You can do "block by block" simulations in Harmonica(Serenade) as well in OrCAD (preferably 9.2 or higher version). Harmonica needs less computing resource, is faster and is very suitable to simulate rf and microwave circuits, especially oscillators, mixers, modulators and...
balun cadence
L0 and L1 are too small (10nH) and their reactance are almost zero at several MHz. These reactances are "in series" with internal resistances of V1 and V4 wich are probably zero. This is the reason why, at low frequencies, the two outputs of the balun can considered to be...
