Vanchip Products

Vanchip offers four main RF product categories: (1) RF Power Amplifiers - high-efficiency PAs for 4G/5G cellular applications with industry-leading linearity and efficiency; (2) RF Switches - high-isolation switches for antenna tuning and signal routing with excellent insertion loss characteristics; (3) RF Filters - SAW and BAW filters for precise frequency selection and interference rejection; (4) RF Front-End Modules - integrated solutions combining PA, switch, and filter functions for simplified design and reduced BOM cost.

Review each product category to find components matching your RF system requirements, or contact our FAE team for integrated solution recommendations.

Selecting the right Vanchip PA requires considering: (1) Frequency band - match your target cellular band (B1, B3, B5, n77, n78, etc.); (2) Output power - ensure the PA meets your conducted power requirements with adequate headroom; (3) Efficiency - evaluate PAE at your operating power level for thermal management; (4) Linearity - check EVM and ACLR specifications for your modulation scheme; (5) Package - select appropriate package size for your PCB constraints. Vanchip offers both discrete PAs and integrated modules for different design needs.

Use our PA selection guide or contact FAE with your band, power, and efficiency requirements for personalized recommendations.

Vanchip discrete PAs are standalone power amplifiers offering maximum flexibility for custom RF designs, allowing engineers to optimize matching networks and combine with preferred switches/filters. FEMs (Front-End Modules) integrate PA, switch, and filter functions in a single package, providing: (1) Reduced design complexity - no external matching required; (2) Smaller PCB footprint - optimized integration saves space; (3) Guaranteed performance - pre-matched and tested; (4) Faster time-to-market - minimal RF tuning needed. Choose discrete for custom designs with specific requirements, FEMs for rapid deployment and space-constrained applications.

Evaluate your design timeline, PCB space, and RF expertise. Contact us for FEM recommendations or discrete component selection.

For antenna tuning applications, consider these Vanchip switch characteristics: (1) Isolation - higher isolation (>30dB) prevents unwanted signal coupling between antenna ports; (2) Insertion loss - lower loss (<0.5dB) preserves transmit power and receive sensitivity; (3) Power handling - ensure switch can handle your maximum transmit power; (4) Switching speed - faster settling time (<10us) for dynamic tuning; (5) Control interface - SPI or GPIO compatibility with your baseband. Vanchip offers SPST, SPDT, SP3T, and SP4T configurations for various antenna architectures including diversity and MIMO systems.

Define your antenna configuration and performance requirements, then consult our switch selection matrix or contact FAE for specific recommendations.

Vanchip provides both SAW (Surface Acoustic Wave) and BAW (Bulk Acoustic Wave) filter technologies: (1) SAW filters - cost-effective for lower frequencies (<2GHz), suitable for 2G/3G/4G bands with good performance; (2) BAW filters - superior performance for higher frequencies (>2GHz) and 5G applications, offering steeper roll-off and better temperature stability. Vanchip filters cover major cellular bands with excellent out-of-band rejection, enabling coexistence of multiple radios in compact devices. Both technologies are available in compact CSP and QFN packages.
