Shipments
Although there has been some improvement, most airlines still have not resumed their flights to Israel, the remaining available flights (local carriers) are prioritized for critical supplies, leading to a severe lack of available cargo space and delays. The delays are due to force majeure and we are doing our utmost best to minimize them as much as possible.
|
We recommend checking your current orders and expediting (where possible) your requested delivery dates. We are at your disposal to expedite shipments as much as possible to ensure their timely delivery. Contact us, and we will be happy to assist with any questions or concerns.
|
Also, please note that between 23/12/23 and 02/01/24, Mini-Circuits will be closed for the holidays. We recommend placing urgent orders before the closure to avoid unwanted delays.
|
As always, we are here for you.

An ideal directional coupler has 0 dB of insertion loss, a constant coupling value vs. frequency, and infinite isolation and directivity. However, the physical, internal construction of directional couplers introduces frequency-dependent losses and finite isolation and directivity. Compounding these internal effects, PCB-mounted couplers face additional challenges. Stray coupling from port to port on a PCB-mounted directional coupler can have significant, adverse effects on the coupler isolation, directivity and even coupling value.
|
Fortunately, many packaging and shielding methods are available to the designer to mitigate stray coupling. This application note examines form-in-place gasketing for two distinct bidirectional coupler styles: the core & wire and the stripline SMT. Modern day form-in-place gasket machinery is capable of depositing very tiny beads with good adhesion over intricate patterns. The use of conductive silicone elastomers is common, and generally results in high-performance RF/microwave shielding. This technique is
|
While this application note emphasizes directional coupler external packaging, form-in-place gasket shielding is used broadly to optimize a myriad of components as well as for entire receive and transmit subsystems. This technique is cost effective, repeatable practical to implement in most industry manufacturing environments.
|
|
In another application note we will explore some of the more traditional methods of shielding couplers including sheet metal fencing with a lid (commonly referred to as a “doghouse”) and surface-mountable conductive silicone elastomers.

Lumped LC Band Pass Filter
120 - 150 MHz, 50Ω
|
|
|
|
|
ZX75BP-135-S+ is a 50Ω bandpass filter in a connectorized package covering 120 to 150MHz. This offers good matching within the passband and high rejection in stopband.

Reflectionless Low Pass Filter
DC - 1050 MHz
|
|
|
|
|
Mini-Circuits’ ZXLF Series reflectionless filters employs a novel filter topology which absorbs and terminates stop band signals internally rather than reflecting them back to the source. Reflectionless filters eliminate stopband reflections, allowing them to be paired with sensitive devices and used in applications that otherwise require circuits such as isolation amplifiers or attenuators. This is developed in a new broadband, …
