MTT-S 2009: Infineon Launches LNA MMIC For Embedded FM Radio Antennae In Handsets

BGB707L7ESD---Application-e

Infineon Technologies AG recently released details on a wideband, low-power consumption Low Noise Amplifier (LNA) ideally suited for FM radio active antenna applications in mobile handsets.

With FM radio receivers emerging as a key feature in the next-generation of cellular phones, there is a general trend to replace the headset cable antenna with miniature embedded FM radio antennas. This requires an external LNA to compensate the embedded antenna performance.

Infineon's new BGB707L7ESD LNA is a wideband, low power consumption general-purpose SiGe:C MMIC LNA in a small TSLP-7-1 package (2.0x1.3x0.4mm). The LNA is as flexible as a discrete transistor and offers numerous integrated features. Circuit designers will appreciate the flexibility and stability of an integrated power-off function for longer battery life, active biasing, a wide operating voltage range and adjustable current. Integrated ESD protection of 3kV at RF input, a high input gain compression point and excellent noise figure make it suitable for a wide range of RF circuit designs.

The BGB707L7ESD will be available in volume quantities from July 2009 onwards. Pricing starts at USD 0.60 per piece for quantities of 1,000 units..

Key features

  • Integrated ESD protection: 3kV for RF input, HBM
  • High input compression point
  • Excellent noise figure: min. NF of 1 dB at 6 GHz
  • Adjustable current: 2.3 to 25mA
  • Power-off function
  • Pb-free (RoHS-compliant) and halogen-free (WEEE-compliant) package

In addition to FM radio in mobile handsets, applications for the BGB707L7ESD include mobile TV, WiFI, WLAN and WiMAX systems.
