PIN Diodes for Attenuators
The new RN77 Series!
The ROHM Diode Manufacturing Department has developed PIN
diodes optimized for car audio and car antenna AGC (Auto Gain
Control) applications. A press announcement will be held in
conjunction with this release. Therefore, it is recommended that
promotion of the products be conducted at this time.
