Mini-Circuits ZX60-123LPNR+ 50MHz–10GHz Amplifier
Manufacturer: Mini-Circuits
Package / Case: GC957 Coaxial Case, SMA Female Connectors
Description: 50 MHz to 10 GHz Low Additive Phase Noise Amplifier, 16.2 dB Gain, −168 dBc/Hz at 10 kHz Offset, +14 dBm P1dB, 6V Supply
The Mini-Circuits ZX60-123LPNR+ is a 50Ω connectorized amplifier covering 50 MHz to 10 GHz. It is designed for signal chains in which amplifier-added phase noise, broadband gain flatness and stable operation are more important than achieving the lowest possible receiver noise figure.
The amplifier uses GaAs HBT technology and provides approximately 16.2 dB typical gain. Its typical additive phase noise is −168 dBc/Hz at a 10 kHz offset, while gain flatness is approximately ±0.8 dB from 50 MHz to 6 GHz. Mini-Circuits also identifies it as a connectorized evaluation module for the GVA-123+ MMIC.

Frequently Asked Questions
What frequency range does the ZX60-123LPNR+ cover?
The specified operating frequency range is 50 MHz to 10 GHz. Its broadband coverage supports communications, satellite, avionics and RF test applications.
What is the additive phase noise of the ZX60-123LPNR+?
The typical additive phase noise is −168 dBc/Hz at a 10 kHz offset. The published test condition uses a 2 GHz carrier with approximately +1 dBm input power.
Is the ZX60-123LPNR+ a low noise amplifier?
It is primarily classified as a low additive phase noise amplifier. Its typical noise figure is approximately 4.3 dB, so it should not automatically be selected as the first-stage LNA in applications requiring the lowest possible receiver noise figure.
What is the difference between ZX60-123LPNR+ and ZX60-123LPN+?
Both models cover 50 MHz to 10 GHz and provide similar gain and phase-noise performance. The ZX60-123LPNR+ operates from a nominal 6V supply and includes internal voltage regulation and reverse-voltage protection, while the ZX60-123LPN+ is the standard 5V version.
Can the ZX60-123LPNR+ evaluate the GVA-123+ MMIC?
Yes. Mini-Circuits identifies the ZX60-123LPNR+ as an evaluation module for the GVA-123+, providing SMA connections, bias circuitry and a connectorized housing for laboratory testing.
