• General-purpose RF amplification capabilities
• Surface-mount construction for automated assembly

Applications

• GPS receiver designs
• RF signal amplification circuits
• General-purpose radio frequency systems

Procurement Notes

Verify the manufacturer designation as Sanyo or Sanyo Denki when sourcing this component. Confirm the specific suffix -TLM-E corresponds to the 16-SSOP package variant. Check product status indicators such as 'Active' or 'Out of Stock' on distributor platforms to ensure availability. Ensure the received unit matches the specified electrical parameters including the 35mA supply current and 61dB gain characteristics.

Selection Notes

Select this component for applications requiring moderate gain and low noise in the VHF band. The 16-SSOP package is suitable for space-constrained PCB layouts. Consider the 4.5V to 5.5V supply requirement when designing power rails. Evaluate the 10dB noise figure against system sensitivity requirements. The 50dBm P1dB indicates handling capability for specific signal levels.

Part Context

This part belongs to the LA7783 series of RF amplifiers from Sanyo. The series targets analog and mixed-signal applications, specifically focusing on radio frequency front-end modules. The TLM-E suffix denotes the specific tape-and-reel packaging and pin configuration compatible with standard surface-mount reflow processes.
