(1) Pulse test: tp ≤ 300µs δ < 2%.
(2) Noise figure test :
- diode is inserted in a tuned stripline circuit
- local oscillator frequency 1GHz
- local oscillator power 1mW
- intermediate frequency amplifier, tuned on 300MHz, has a noise figure 1.5dB
Matched batches available on request. Test conditions (forward voltage and/or capacitance) according to customer specification.
