CHA3513-99F
CHA3513-99F is 3-bit Digital Variable Amplifier manufactured by United Monolithic Semiconductors.
6-18GHz 3 bit Digital Variable Amplifier
Ga As Monolithic Microwave IC
Description
The CHA3513-99F is posed by a three
10A
5A
10A1 B C F G steps digital attenuator followed by a three
RF stage travelling amplifier and a Single Pole RF Single Through (SPST) switch. It is designed IN 10d B 5d B 10d B
OUT for defense applications. The backside of the chip is both RF and DC grounded. This helps to simplify the assembly process.
