The Q-Bit Corporation QB-9257 is an RF coaxial low noise amplifier engineered for signal chain applications requiring minimal noise introduction and high signal integrity. Operating across 10 MHz to 2 GHz, the unit delivers 20 dB of gain through SMA connectors, making it suitable for test and measurement setups, radio communication systems, and RF signal processing where noise performance is critical.
Technical Specifications
• Frequency Range: 10 MHz to 2 GHz
• Gain: 20 dB
• RF Connectors: SMA (SubMiniature version A)
• Output Power: 1 dB compression point of 25 dBm
• Input/Output Impedance: 50 Ohms
– Key Features
• Low noise design minimizes signal degradation in receive chains
• Wideband operation spans a decade from VHF through microwave frequencies
• SMA connector interface simplifies integration into standard RF systems
• Fixed gain topology reduces complexity in signal path design
– Typical Applications
• Test and measurement equipment requiring sensitive signal detection
