RLB1500 Specifications

Operating Range: 0.5 - 1500 MHz

Insertion Loss: 18 dB@ 5 MHz to 21 dB @ 1.5 GHz

Directivity: 35 dB minimum from 500 kHz - 1.5 GHz, typical directivity exceeds 40 dB over 80 % of range

Input port return loss: 14 dB minimum

Output port return loss: 10 dB minimum

Weight: 9 ounces

Dimensions: 4.75 x 2.6 x 1.55 inches (case size) or 4.75 x 3.8 x 1.55 inches (case and connectors)

Input to output
connector spacing: 2.95 inches center to center

Construction: Aluminum die-cast case

Connectors: All are high-quality type N female, nickel plated brass, with gold plated center pin

Accidental input power
to DUT port capability: 3.5 Watts continuous - 4 to 5 Watts intermittent.

Open / Short Differential: (for calibration) 2 dB maximum at 1.5 GHz, 1.2 dB typical at 1.5 GHz (worse case)

DC voltage isolation: DUT port is DC blocked (AC coupled) allowing +/- 16 VDC Maximum (at DUT port only)

Maximum RF power
to "Input" port capability: 1 Watt (+30dBm) continuous

Shock: Withstands 48 inch drop to 1/2 inch plywood-covered concrete on each of 6 surfaces

Waterproof: No

Color: Dark Gray - Rubberized coating.

Warranty: 1 year parts and labor (does not cover connector damage, over-power on any port, or abuse)

Out of warranty repair: Determined on a case by case basis, but generally the bridge can be repaired for anything other than connector damage for a flat fee of $125.00 plus return shipping ($18.00 US). This fee includes recalibration and recertification.
