Description

​

• The CMTBA1S, a single stage SiGe low noise amplifier, is intended for extremely low noise cryogenic applications where lower gain and lower power dissipation is required. The amplifier uses resistive feedback to achieve good input match (S11) and high gain stability. Typlical input return loss is -20 dB. The amplifier is optimum for the frequency range of 0.005 GHz to 1.0 GHz.  The amplifier has good noise performance up to 3 GHz.
   

• It is powered from a single positive DC power supply which is optimum at 3.0 V.
   

• The amplifier is available in a miniature configuration, with or without integrated resistive bias tees.

Optional Input Protection Diodes

​

As an option, the amplifier can be supplied with ESD protection & voltage spike protection at the RF input to the amplifier. There will be a slight degradation of the amplifier performance. Please note that the optional input protection diodes cannot be used if DC voltages are applied to the RF line using input bias tees.

 

To order an amplifier with internal protection diodes, add the resistance to the part #. For instance, CMT-BA1S-PD.
