Description

M/A-COM’s AT65 -0008 is a PIN diode based voltage variable attenuator. It is packaged in an 8 le ad small outline narrow body plastic, surface mount package. The attenuator has linear operating power and intercept point level s higher than GaAs FET MMIC based voltage variable attenuators. The VVA is suited for use where low distortion and high linear operating power are required. The device operating frequency is selected in the 900 to 2500 MHz frequency band by defining the length of the T/4 (a quarter wave transmission line at the operating frequency) connected to pins 5 and 6. Package outline conforms to JEDEC standard MS-012AA.
