MPG / K&L Microwave 8LB30-6.3/U4-O/O Lumped Component Filter Description

Functions

Lumped component bandpass filter operating at 6.3 GHz center frequency with selective frequency transmission characteristics, designed to pass signals within a specified bandwidth while attenuating frequencies outside this range. Utilized in RF/microwave systems for signal conditioning, interference rejection, and channel selection. Features high Q passive components (inductors, capacitors) arranged in a precise topology to achieve desired frequency response with minimal insertion loss. Suitable for communications equipment, radar systems, test instrumentation, and military applications requiring reliable signal filtering in confined spaces.

Applications

Provides precise frequency selectivity and signal conditioning in RF and microwave systems operating from DC to several GHz. Typically employed in communication transceivers, test equipment, and instrumentation to attenuate unwanted harmonics, suppress spurious emissions, and isolate desired signal bands. Essential for EMI/EMC compliance, mixer filtering, oscillator cleanup, and preventing intermodulation distortion in multi-channel systems. Used in military radar, satellite communication, cellular infrastructure, and laboratory measurement setups where compact size and consistent performance across temperature variations are critical requirements.

Interfaces

RF input/output via SMA female connectors, 50 ohm impedance, threaded coupling mechanism. DC power not required for passive filter operation. No control interfaces. Hermetically sealed enclosure with mounting holes for chassis integration. Operating temperature range typically -55°C to +85°C. U4 option indicates custom electrical specification modification from standard 8LB30-6.3 design parameters.

Specifications

High-performance lumped component bandpass filter operating within a frequency range of approximately 6.3 GHz, designed for signal conditioning in RF systems. Features precision filtering capabilities with steep roll-off characteristics and minimal insertion loss. Implements a highpass-lowpass topology with 8 reactive elements for optimal passband flatness and stopband rejection. Constructed with high-Q components in a ruggedized housing for environmental stability. Interfaces via industry-standard RF connectors, typically SMA or N-type. Primarily used in military communications, radar systems, wireless infrastructure, and test equipment applications requiring precise signal selectivity and interference mitigation.
