2D528B Microwave Step Recovery Diode 200GHz USSR NOS

Description

Russian Microwave Step Recovery Diode 2D528B
In electronics, a step recovery diode (SRD) is a semiconductor junction diode having the ability to generate extremely short pulses. It is also called snap-off diode or charge-storage diode or memory varactor, and has a variety of uses in microwave electronics as pulse generator or parametric amplifier. When diodes switch from forward conduction to reverse cut-off, a reverse current flows briefly as stored charge is removed. It is the abruptness with which this reverse current ceases which characterises the step recovery diode.
Are intended for pulse shaping of
subnanosecond
pulses.

This still affects delivery and courier companies and Customs Transit/Clearance  Areas where only essential staff present.
The tracking update information grossly neglected by Postal and delivery companies in your respective countries which causes further frustration to you and us.
The worst countries with delayed deliveries are:
UK, Italy, FRANCE, Greece, Germany, Canada, Malaysia, Indonesia, Taiwan, etc
. with up to 40 working days for delivery (50-54 calendar days).
This doesn't meant it happens to every parcel we sent out but it does take place with many.
Please take in to account while processing a purchase that it will take considerably longer for your parcel to be delivered than usual.
We still process your orders within 48 hrs and everything possible to get your purchases on the way for prompt delivery.
