Infineon BGA614H6327: 4 GHz Broadband SiGe Bipolar Gain Block Amplifier
In the realm of high-frequency electronics, achieving robust signal amplification across a broad spectrum is a critical requirement for applications ranging from wireless infrastructure to test and measurement equipment. The Infineon BGA614H6327 stands out as a premier solution, a Broadband SiGe Bipolar Gain Block Amplifier engineered to deliver exceptional performance from DC up to 4 GHz.
This amplifier is designed to provide a high gain of 20.5 dB typical at 900 MHz, ensuring that weak signals are significantly boosted with minimal added noise, thanks to its low noise figure of just 2.6 dB. Constructed using advanced Silicon-Germanium (SiGe) bipolar technology, the BGA614H6327 offers a superior combination of high-frequency operation, breakdown robustness, and excellent thermal properties compared to traditional GaAs or silicon-based alternatives.

A key feature of this gain block is its simplicity of integration. It is internally matched to 50 Ω, requiring only a few external bias components to become fully operational, which drastically simplifies PCB design and reduces time-to-market. Furthermore, it operates from a single positive supply voltage as low as +3 V to +5 V, making it highly suitable for portable and battery-powered devices. Its high output IP3 (OIP3) of up to +26 dBm ensures superior linearity, minimizing distortion and preserving signal integrity in demanding RF environments.
The BGA614H6327 is housed in a compact, lead-free SOT-343 (SC-70) package, ideal for space-constrained applications. Whether used as a driver amplifier, a LO buffer, or within CATV/WLAN systems, this component provides a reliable and high-performance building block for a multitude of RF designs.
ICGOODFIND: The Infineon BGA614H6327 is an outstanding broadband gain block that excels through its high gain, low noise, and ease of use, making it an excellent choice for designers seeking performance and integration simplicity from DC to 4 GHz.
