Mini-circuits ZHL-0812MLN

The Mini-Circuits ZHL-0812MLN is a wideband low-noise amplifier engineered for UHF, cellular, and PCS/GSM systems operating between 800 and 1200 MHz. This coaxial amplifier delivers 27 dB typical gain with exceptional noise performance—0.52 dB noise figure at 800 MHz—making it ideal for sensitive receiver applications. The device saturates at +20 dBm output power (1 dB compression) and achieves a third-order intercept point of 38.65 dBm at 800 MHz.

– Technical Specifications

• Gain: 27 dB typical (44.97 dB at 800 MHz; 47.60 dB at 1200 MHz)
• Noise Figure: 0.52 dB at 800 MHz; 0.47 dB at 820 MHz; 1.6 dB maximum
• Output Power (P1dB): +20 dBm typical (26.98 dBm at 800 MHz)
• IP3: 38.65 dBm at 800 MHz
• Input VSWR: 1.5:1 typical (1.22:1 at 800 MHz)
• Output VSWR: 1.6:1 typical (1.32:1 at 800 MHz)
• DC Supply: 15V nominal (17V maximum); 300 mA typical
• Input RF Power Rating: 0 dBm maximum; open load derating requires 20 dB reduction
• Operating Temperature: −20°C to +65°C
• Storage Temperature: −55°C to +100°C

– Key Features

• SMA connectors for straightforward integration
• Low noise figure enables weak-signal detection in receiver chains
• Moderate compression power suitable for linear and saturated applications
• Excellent input/output impedance matching across the band
• FJ893 package format

– Typical Applications

• UHF communication systems
• Cellular and GSM base station receivers
• PCS receiver front ends
• Low-noise signal acquisition in test and measurement

– Compatibility & Integration

The amplifier mounts in systems using standard SMA-connectorized RF modules. Bias decoupling and impedance matching networks are required per datasheet recommendations. Permanent damage occurs if DC voltage exceeds 17V or input RF power exceeds 0 dBm; open-load conditions demand 20 dB power derating.
