KRYTAR 2-Way Power Dividers | 0.4–45GHz Model Guide
KRYTAR 2-Way Power Dividers: 0.4 to 45 GHz Model Selection Guide
KRYTAR 2-way power dividers are broadband passive microwave components designed to divide one RF input signal into two nominally equal, in-phase output signals. When operated in the reverse direction under suitable signal conditions, they may also be used as RF power combiners.
KRYTAR offers an extensive range of Wilkinson and proprietary Matched-Line Directional Divider—MLDD—products for RF, microwave and millimeter-wave systems. Available models extend from approximately 0.4 GHz to 45 GHz, supporting applications from wireless communication and laboratory testing to radar, electronic warfare, SATCOM and antenna beamforming.
The KRYTAR 2-way power-divider family is particularly suitable for systems requiring:
Ultra-broadband frequency coverage
Equal two-channel signal distribution
Low additional insertion loss
High output-port isolation
Low amplitude and phase imbalance
Compact coaxial construction
SMA, 2.92 mm or 2.4 mm connectivity, depending on model

Frequently Asked Questions
What is the frequency range of KRYTAR 2-way power dividers?
Standard KRYTAR two-way divider models cover individual bands from approximately 0.4–7.125 GHz up to 3–45 GHz. The main product family is commonly specified as covering 0.5 to 45 GHz, while the listed 600407125 model extends operation down to 0.4 GHz.
Does a 2-way power divider always have 3 dB loss?
An ideal equal two-way split introduces approximately 3.01 dB of division loss at each output. Real devices also have additional circuit and material loss. KRYTAR’s published power-divider insertion-loss figures exclude the theoretical split loss.
Which KRYTAR model covers 6 to 40 GHz?
Models 6060400 and 6060400K cover 6 to 40 GHz. The K version offers a 2.92 mm connector configuration and published specifications of up to 1.9 dB additional insertion loss, at least 14.5 dB isolation and 0.5 dB amplitude tracking.
Which model provides the widest frequency coverage?
Model 6010400 covers 1 to 40 GHz, while Model 6030450 extends from 3 to 45 GHz. The best choice depends on whether low-frequency coverage below 3 GHz or upper-frequency coverage above 40 GHz is more important.
When should I choose a KRYTAR ULTRA+ power divider?
Choose an ULTRA+ model when the application requires tighter amplitude balance, phase tracking, VSWR or isolation specifications than the corresponding standard product.
