DESCRIPTION
The STDD15 is a dual diode series for the
detection of a RF signal and the compensation of
thevoltagedriftwiththe temperature. TheSOT323
package makes the device ideal in application
where the space saving is critical like mobile
phones.
The low junction capacitance will reduce the
disturbance on the RF signal
