ZHL-32A-S+

Overview

The ZHL-32A-S+ is a medium power linear RF amplifier from Mini-Circuits, designed for frequencies ranging from 50 kHz to 130 MHz. It features a gain of 25 dB with flatness within ±1 dB and an output power of 29 dBm. The device operates on a 24 VDC supply with a current draw of 600 mA. It utilizes SMA connectors and is housed in the S32 case style, maintaining a 50Ω impedance throughout its operational bandwidth.

Feature Summary

• Provides linear amplification across the HF and VHF spectrum
• Maintains stable gain performance with low flatness deviation
• Delivers high output power suitable for demanding RF applications

Applications

• RF signal generation and conditioning
• Test and measurement instrumentation
• Communication system front-ends

Procurement Notes

Verify the specific suffix 'S+' indicates SMA connectors rather than BNC variants like the ZHL-32A+. Confirm the S32 package style matches your mechanical constraints. Ensure the 24 VDC supply requirement aligns with your power budget. Check availability status as this series may have limited stock due to manufacturing constraints.

Selection Notes

Select this model when operating between 50 kHz and 130 MHz with a need for 29 dBm output. Choose over the BNC version if SMA connectivity is required. Consider thermal management for continuous 600 mA operation. Validate that the 25 dB gain meets your system noise and signal requirements without excessive downstream amplification.

Part Context

This component belongs to the ZHL Series, which offers medium to high power amplification up to 4200 MHz. The ZHL-32A-S+ specifically targets lower frequency bands compared to higher-frequency siblings. It shares the S32 case style with other models in the lineup but differs in connector type and frequency range specifications.

Replacement Considerations

The ZHL-32A+ serves as a direct functional substitute with identical electrical characteristics but uses BNC connectors instead of SMA. Verify connector compatibility before swapping. No other official substitutes are documented for this specific configuration.
