ZVA-183WA-S+

Overview

The ZVA-183WA-S+ is a coaxial, wideband RF amplifier from Mini-Circuits designed for operation between 100 MHz and 18 GHz. It features SMA connectors and a 50Ω impedance. The device provides 25 dB of gain with a typical noise figure of 4.5 dB. It delivers an output power of 29 dBm at the P1dB compression point and achieves a third-order intercept point (IP3) of 42 dBm. Power consumption requires a 12 VDC supply drawing approximately 950 mA.

Feature Summary

• Wideband linear amplification across 100 MHz to 18 GHz
• Low noise figure suitable for sensitive receiver applications
• High linearity with elevated IP3 performance
• Medium power output capability for signal driving

Applications

• Test and measurement instrumentation
• Wireless communication systems
• Broadband data transmission links
• Military and aerospace radar subsystems

Procurement Notes

Verify the specific suffix designation against the manufacturer's current documentation to ensure compatibility with required frequency ranges and connector types. Confirm that the 12 VDC power supply specifications align with system constraints before integration. Cross-reference the case style AV2554-3 with PCB layout requirements to ensure proper mechanical fit and thermal management.

Selection Notes

Select this component when a single-stage solution is required for ultra-wideband coverage up to 18 GHz. Consider the 29 dBm output power limit for load matching and the 950 mA current draw for power budget calculations. Evaluate the 4.5 dB noise figure against system sensitivity requirements. Compare against lower-frequency alternatives if bandwidth needs are restricted below 6 GHz.

Part Context

This model belongs to the ZVA series of medium power amplifiers by Mini-Circuits. It serves as a high-performance active component within RF front-end architectures. The device bridges the gap between low-noise pre-amplifiers and high-power final stages, offering balanced gain and linearity characteristics for complex signal processing tasks.

Replacement Considerations

The ZVA-183W-S+ is a related variant within the same product family. Verify functional equivalence regarding gain flatness and power handling before substitution. Ensure connector types and mounting dimensions match the existing design infrastructure.
