Integrated balun from STMicroelectronics saves 70% of board space, simplifies design and maximizes RF performance

 

The BAL-2690D3U is a balun designed to transform a single-ended signal to differential signals in Bluetooth applications.

With less than 1.1 dB insertion losses in the 2400 MHz to 2500 MHz bandwidth, it has been customized for the STLC2690 Bluetooth transceiver and specific requirements for the SCC22 parameter at 2f0 (4.88 GHz).

The BAL-2690D3U integrates a full impedance matching network, so no external components are required on the PCB. Both overall performances and PCB area are optimized.

Features
  50 Ω nominal input, 30+j25 output differential impedance
  Low insertion loss
  Low amplitude imbalance
  Low phase imbalance
  Small footprint: BAL-2690D3U < 1.0 mm²
 
Benefits
  Very low profile (<700 µm)
  High RF performances
  RF component count and area reduction
