Dolph Microwave have resumed production and delivered the order products ASAP, Most waveguide components delivery lead time are still within 4 weeks. welcome any requirement. Delivered waveguide coaxial adapter details for your reference.

Because this type of antenna has a relatively high gain, when used for electromagnetic compatibility EMC leakage measurement, it can effectively reduce the system noise figure. This is an important function when measuring small electromagnetic leakage. The antenna has stable performance in a high-power environment, and can be used as a standard EMC test transmitting

The logarithmic periodic antenna is the main preferred form of the low frequency uwb directional antenna. The antenna family can cover octave bandwidth or even uwb bandwidth of nearly 100 octaves. The gain can be as high as 9dB. At ultra-low frequencies, a hybrid design is adopted to achieve a high integration of the antenna

In the 3GPP protocol,the overall spectrum resources of 5G can be divided into two FR (Frequency Range) FR1: The Sub6G frequency band is the main frequency band of 5G and is a low-frequency band，the frequency below 3GHz is Sub3G, and the remaining frequency bands are called C-bands. FR2: Millimeter wave is an extended frequency band

Dolph Microwave is vertically integrated and mostly self-sufficient, where virtually all key processes are performed in-house, allowing for maximum control over the design and fabrication of the end product. FABRICATION: CNC machining utilising high accuracy 4 and 3 Axis machines Lathes,Turning facilities Waveguide forming and bending Anodising and Passivation (RoHS) Dip, Welding, Induction & Torch

The multi-beam feed system to provide access to multiple satellites from a single antenna. Access 3 satellites over 10° of arc coverage with outstanding video response. Typical configuration may receive IS-21, IS-23, IS-34. MULTI-BEAM ANTENNA FEATURES: Multi-Sat performance kits designed for ease of installation & maximum flexibility Feature discreet azimuth, elevation, focal length and polarization

With the 5G cellular base station testing and large-scale deployment of mobile communication operators. The interference of the 5G spectrum with the FSS Ext.C band (3.4-3.7 GHz) or the standard C band (3.7-4.2 GHz) will become more and more serious. To solve the problem of co-channel interference and adjacent-channel interference in the 5G spectrum, Dolph

Low noise down-conversion module (LNB) in satellite receiving systems with limited frequency selection capability, The signals in the range of 3.0-4.5 GHz shown in Fig. 1(a) are subjected to reception, amplification and down-conversion. Radio regulations and licensing conditions, based on standard (NR) 5G carriers are mainly in the 3.4-3.6 GHz band and are still within

In order to provide the fastest products and services to our customers, Dolph Microwave stocked a series of products flexible twistable waveguide; the fastest delivery is on next day. Flexible Twistable Waveguide – Model: DH-137WEL1000MMC – Freq. Range: 4.64-7.05 GHz – VSWR: 1.1 – Insertion Loss: 0.18dB/m – Length: 1000 mm – Power Capacity: ≤5

The ring- focus antenna is usually called the parabolic focal axis offset axisymmetric dual mirror antenna. Since the focal trajectory of the antenna is a circle, it is called the circular focus antenna. The ring-focus antenna has its unique position in the satellite communication earth station antenna. Especially in the small and medium satellite communication
