Low Noise Amplifier with Integrated Bypass Switch

Tue, 07/31/2001 - 4:30am
Motorola's Semiconductor Products Sector has announced the introduction of its first SiGe:C standard product for the merchant market. Motorola is introducing a SiGe:C low noise amplifier (LNA) with an on-chip bypass switch. This device utilizes the SiGe:C module of Motorola's advanced 0.35 micron RF BiCMOS process. The SiGe:C technology requires the addition of only one masking step into a proven mainstream process.

The advanced device is an LNA with an integrated bypass switch. The on-chip bypass switch improves the dynamic range, with low insertion loss, for receiver designs. In addition to providing improved performance, the integrated bypass switch helps conserve board space and reduce system and manufacturing costs. This device also includes high gain, high input IP3, low noise figure, selectable current settings, and a standby mode to turn the device completely off. Input and output matching is performed externally to allow maximum design flexibility.

The IC can operate from 400 to 2400 MHz. Applications include PCS 1900 MHz cellular telephones as well as 900 and 2400 MHz Industrial, Scientific, and Medical (ISM) Band designs.

The MBC13720 is packaged in an ultra-small SOT-363 surface mount package and is available in tape and reel.
