The Mini-Circuits ZHL-1724MLN is a coaxial, low-noise RF amplifier covering 1700 to 2400 MHz with 50 Ω impedance and SMA connectors. Designed for PCS/DCS, UMTS, and defense applications, this amplifier delivers 28 dB typical gain with ±1.0 dB flatness and a maximum noise figure of 1.5 dB. It operates from a single +8V to +15V DC supply (17V maximum rating) and produces typical output power at 1 dB compression between 21.4 and 23.4 dBm at 15V across the frequency range.

– Key Features
• Exceptional linearity with +32 to +38 dBm IP3
• Low-noise performance suitable for sensitive receiver applications
• Minimal VSWR across the 1700–2400 MHz band ensures efficient signal coupling
• Wide supply voltage range accommodates various system configurations
• Shielded package minimizes electromagnetic interference
• User-supplied heat sink required to maintain baseplate temperature ≤65°C
– Typical Applications
• PCS/DCS base stations and infrastructure
• UMTS communication systems
• Radar and instrumentation

– Compatibility & Integration
The ZHL-1724MLN integrates directly into 50 Ω systems via SMA connectors. Single positive supply operation simplifies DC distribution. Gain flatness of ±1.0 dB across the 700 MHz bandwidth enables use in broadband applications without per-frequency equalization. External heat sinking is mandatory for operation in the upper temperature range.
