EMC Technology & Florida RF LabsJointly developedHMR2FRadio Frequency Module

It is a...90-degree mixed coupler(90° Hybrid Coupler), a type of RF / microwave passive device, primarily used for the distribution and synthesis of high-frequency signals. Its core functions include:

1. Signal Distribution and Synthesis

• Power DistributionThe input signal is evenly distributed across two output ports.

• Phase ControlAchieve inter-signal connectivity90-degree phase differenceSuited for applications requiring orthogonal signals (such as orthogonal modulation/demodulation, polarization separation, etc.).

• Reflective Signal MonitoringBy extracting a portion of the reflected power at the port, it is used for VSWR measurement or signal integrity monitoring.

2. High-frequency performance features

• Wideband CoverageBased on speculation from similar products (such as the HMQ series), the HMR2F may support...2.7–3.2 GHzFrequency (specifically as per the official specification sheet), applicable to C-Band or specific communication frequencies.2。

• Low Insertion LossTypical Insertion Loss ≤ 0.14 dB (refer to HMQ Series specifications), ensuring signal transmission efficiency.

• High isolationInter-port isolation ≥20 dB, reducing signal crosstalk and enhancing system stability.

3. Reliability Design

• Wide Temperature Operating RangeSupport-55°C to +85°CExtreme temperature environments, suitable for rigorous applications in industries such as industrial and aerospace.3。

• High-power processing capabilityAffordable200–250 WPeak power (comparable to the HMQ series of similar products), suitable for high-power transmission systems.

• Antijamming and StabilityUtilizing stainless steel or nickel-plated casings, coupled with low dielectric materials, the product reduces electromagnetic leakage and signal distortion.
