Coaxial Power Splitter/Combiner 2 Way-0o 509 10 to 1000 MHz

Category: Electronics, Minicircuits, RF Microwave Devices

General Overview

The datasheet describes the Coaxial Power Splitter/Combiner 2 Way-0o 509, with a frequency range of 10 to 1000 MHz. Specifically, this device is designed to either combine two signals into one or split a signal into two equal parts across the specified frequency range. The specific model number featured in this datasheet is ZFSC-2-2+, with variations like ZFSC-2-2-S+ (SMA connectors) and ZFSC-2-2-N+ (N-TYPE connectors), which differ in the types of connectors used.

Maximum Ratings

The device can operate in temperatures ranging from 55°C to 100°C and should be stored within the same temperature range to avoid damage. It has a maximum power input of 1 Watt when used as a splitter and the internal dissipation should not exceed 0.125 Watts. Exceeding these specifications may lead to permanent damage.

Features

The splitter/combiner is characterized by a wide bandwidth, low insertion loss (0.4 dB typical), and excellent isolation (28 dB typical). It provides excellent amplitude (0.1 dB typical) and phase unbalance (0.5 degrees typical), along with very good return loss and Voltage Standing Wave Ratio (VSWR, 1.2:1 typical). Made to be robust, it’s housed in a rugged shielded case and is compliant with the Restriction of Hazardous Substances (RoHS) directive.

Applications

This device is suitable for applications in cellular systems, VHFI/UHF, and instrumentation fields where signal splitting or combining is required.

Electrical Specifications

When detailing the electrical specifications for the frequency range of 10-1000 MHz, the datasheet provides information on isolation, insertion loss, phase unbalance, and amplitude unbalance. Typical insertion loss remains below 0.5 dB for this range, and isolation is generally greater than 26 dB. The amplitude and phase unbalance are also maintained within acceptable limits for most applications in the given frequency range.

Performance Data & Outline Dimensions

The datasheet includes performance data for various frequencies, illustrating specific values of total loss, amplitude unbalance, isolation, and phase unbalance. It also provides outline drawings and dimensions for the device, including the adjustments needed for option B with N-type connectors. The weight of the device is 70 grams.
