VHF-1200+

Overview

The VHF-1200+ is an LTCC high-pass filter manufactured by Mini-Circuits. It operates within a frequency range of 1380 MHz to 4000 MHz. The component features SMA connectors and is designed for in-line module applications. Key electrical specifications include a cutoff frequency of approximately 1.18 GHz, a bandwidth of 3.38 GHz, and an insertion loss rating of 3.08 dB. The device offers temperature stability and excellent power handling capabilities suitable for RF signal processing.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for robust construction
• Provides high-pass filtering functionality with defined cutoff characteristics
• Incorporates SMA connectors for standard interface compatibility

Applications

• RF communication systems requiring signal band separation
• Microwave circuit design for frequency selection
• Signal integrity enhancement in radio frequency modules

Procurement Notes

Verify the specific datasheet revision and connector type before procurement, as documentation indicates potential variations in connector configurations across different production batches or sub-models. Ensure the required frequency range aligns with the 1380 MHz to 4000 MHz specification. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Cross-reference the part number suffixes with official Mini-Circuits literature to ensure functional equivalence.

Selection Notes

Select this component when a high-pass response is required between 1.38 GHz and 4 GHz. Consider the 3.08 dB insertion loss impact on system gain budgets. Evaluate the physical footprint and SMA interface against PCB layout constraints. Compare performance metrics such as rejection levels against alternative filters if stringent stopband attenuation is necessary for the specific application environment.

Part Context

This component belongs to Mini-Circuits' VHF series of high-pass filters. The series includes variants like VHF-650 and VHF-880, offering different cutoff frequencies. These components are generally characterized by their use of LTCC technology, which provides compact size and reliable thermal performance compared to traditional waveguide or coaxial designs.
