The 1N4148 even with bias doesn't come anywhere close to performance of the 1N60 for a low level signal. We tried that and the signal type HP Schottky diodes, (also with and without bias). I'd maybe prefer the 1N4148 for an FM discriminator / ratio detector, low power SMPSU up to 100mA @ 100V PIV, ordinary low power rectifiers for bridges and charge pumps for AC linear PSUs, clamps, meter protection (though I might use 1N400x), AM Video detectors, RF switches where the DC biases are much higher than RF signal (PIN diodes are better as the RF can exceed DC) DTL logic, diode programming matrixes etc.
