Herotek DZR50024A 10MHz–50GHz Zero-Bias Detector
Herotek DZR50024A 10MHz–50GHz Zero-Bias Detector
The Herotek DZR50024A is a broadband zero-bias Schottky diode detector operating from 10MHz to 50GHz. It converts RF and millimeter-wave signals into a DC output without requiring an external bias supply.
With its wide frequency coverage, 2.4mm RF input and compact coaxial package, the DZR50024A is designed for microwave and millimeter-wave test equipment, transmitter monitoring, signal-level detection and radar subsystem testing.

Features and Applications
The DZR50024A combines zero-bias operation with broadband coverage extending into the millimeter-wave range. Its matched RF input helps maintain controlled VSWR, while the flat frequency response supports consistent signal monitoring across multiple microwave bands.
Typical applications include:
Microwave and millimeter-wave test equipment
Transmitter output monitoring
RF power and signal-level detection
Radar subsystem testing
Laboratory measurement systems
Built-in test and fault-monitoring circuits
Because no external DC bias is required, the detector can simplify system integration and reduce additional power-supply circuitry.
DZR50024A Selection Notes
The standard DZR50024A provides negative output polarity. For applications requiring positive polarity, the DZR50024AP version can be specified.
The DZR50024A uses a 2.4mm male RF input and an SMA female output. Other connector configurations in the same family include:
| Model | RF Input | Output |
| DZR50024A | 2.4mm male | SMA female |
| DZR50024B | 2.4mm male | BNC female |
| DZR50024C | 2.4mm male | SMC male |
DZR50024A vs DZR400KA
The DZR50024A and DZR400KA are both broadband zero-bias Schottky detectors, but they differ in frequency coverage and RF interface.
| Model | Frequency Range | RF Input | Sensitivity |
| DZR400KA | 10MHz–40GHz | 2.9mm K male | 0.4mV/µW |
| DZR50024A | 10MHz–50GHz | 2.4mm male | 0.5mV/µW |

Frequently Asked Questions
Does the DZR50024A require an external bias supply?
No. The DZR50024A is a zero-bias Schottky diode detector and operates without an external DC bias supply.
What frequency range does the DZR50024A cover?
It operates from 10MHz to 50GHz, covering RF, microwave and millimeter-wave applications.
What connectors are used on the DZR50024A?
The detector uses a 2.4mm male connector for the RF input and an SMA female connector for the output.
What is the output polarity?
The standard DZR50024A provides negative output polarity. A positive-polarity version can be ordered as DZR50024AP.
What is the maximum CW input power?
The specified maximum continuous-wave input power for the DZR detector series is 200mW.
How does DZR50024A differ from DZR50024B and DZR50024C?
All three models cover 10MHz to 50GHz and use a 2.4mm male RF input. The difference is the output connector: DZR50024A uses SMA female, DZR50024B uses BNC female and DZR50024C uses SMC male.
