VHFG-1780+

Overview

The VHFG-1780+ is a high-pass filter manufactured by Mini-Circuits, designed for RF signal conditioning applications. It operates within a frequency range of 1980 MHz to 11000 MHz, providing a bandwidth of 9020 MHz. The component features low insertion loss with a typical value of 1 dB and offers good return loss of 14 dB typically. It supports a power handling capability of 4 W and utilizes an SMA connector interface.

Feature Summary

• Constructed using rugged unibody design for durability
• Utilizes LTCC technology for miniature form factor
• Provides high stop-band rejection for effective filtering

Applications

• RF signal conditioning in communication systems
• High-frequency filtering in test and measurement equipment
• Signal integrity management in wireless infrastructure

Procurement Notes

Verify the specific datasheet version from Mini-Circuits or authorized distributors to confirm current RoHS compliance status and moisture sensitivity level. Ensure the SMA connector type matches your system requirements. Cross-reference part numbers carefully as suffixes may indicate packaging variations rather than functional changes. Confirm environmental classifications before integration into regulated products.

Selection Notes

Select this component when a high-pass filter with a cutoff near 1.98 GHz is required. Consider its 4 W power handling if driving high-power signals. The LTCC construction suits applications needing compact size. Verify that the SMA interface aligns with existing board layouts. Compare insertion loss specifications against system noise budget requirements.

Part Context

This model belongs to Mini-Circuits' VHFG series of high-pass filters. These components are engineered for high-frequency performance using low temperature co-fired ceramic (LTCC) technology. The series emphasizes robust construction and consistent electrical characteristics across the operating bandwidth, suitable for demanding RF environments.

Replacement Considerations

The HFCG-1780+ is a related Mini-Circuits high-pass filter with similar frequency coverage but different construction. Verify compatibility regarding connector type and mounting style before substitution. Electrical parameters such as insertion loss and power handling should be compared directly.
