Description
M/A-COM鈥檚 AT65-0008 is a PIN diode based voltage
variable attenuator. It is packaged in an 8 lead small outline
narrow body plastic, surface mount package. The attenuator
has linear operating power and intercept point levels 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.
