WE PROVIDE THE BROADCASTING FM & AM & TELEVISION ENGINEERING SERVICES & RF MEASUREMENTS:

WE PROVIDE THE MANUFACTURING BASED ON CUSTOMER SPECIFICATION OF BANDPASS FILTER - NOTCH FILTER - LOW OR HIGH PASS FILTER.

Specifying an RF/ microwave filter, as with any high-frequency component, involves setting desired values for a list of key specifications, both electrical and mechanical. Electrical specifications for a bandpass filter, for example, include total frequency range, pass band insertion loss, out-of-band rejection, bandwidth for a given maximum insertion loss ( such as 3 or 6 dB) , return loss or VSWR, and power-handling capability. Mechanical specifications include physical size, package type, type of connectors and location on the package. Some of the electrical characteristics are related to the mechanical specifications. For example, although surface-mount filters can save a great deal of space in an RF/ microwave system, such filters will be limited in power handling compared to a larger filter with connectors.

* * Our company provides radio field strength measurement services using a range of signal measurement and analysis equipments configured to individual client requirements. Coverage testing can be provided for most types of radio networks including mobile radio, cellular and Wireless LANs.

* * Provides industry leading radio coverage prediction services using best-of breed propagation models, detailed terrain analysis producing readable presentation plots.

* * We uses carrier-grade radio frequency network modelling tools such as Planet Mentum, Pathloss 4 and MapInfo Professional. Prediction models include Okumura-Hata, Longley- Rice ( Point-to-Point and Area mode) , Free Space, ITU recommendation 370, Cost 231 ( Walfish-Ikegami) and Lee.

* * Point-to-multipoint studies for MMDS, LMDS, and WLL systems.

* * Frequency coverage: 300 KHz to 4 GHz.

* * ANTENNA MEASUREMENTS

* * COAXIAL FEEDER - RIGID COAXIAL LINE.

* * BANDPASS - NOTCH FILTER FILTER - CAVITY RE TUNING.

* * COAXIAL LINE OR WAVEGUIDE ANALYSIS

* * VSWR - INSERTION LOSS - DTF & IMPEDANCE ANALYSIS

* * TRANSMITTER PARAMETER MEASUREMENTS.

* * EQUAL PHASE DELAY COAX JUMPER LINES

* * Complete selection of the most accurate propagation prediction models, including capability to create custom propagation model algorithms.

* * Most coverage study capabilities include shadowing, path loss, BER, field strength, received power, C/ ( I+ N) , percent service availability, group-to-group interference, base-to-mobile and mobile-to-base signal levels.

* * Full microwave path analysis including path profile, rain and fade outage, percent availability, dispersive fade margin, antenna diversity reception, and cross-link interference.

* * COAXIAL - RIGID LINE Transmission Line Measurements: If you suspect that you have a problem in one of your transmission lines, comprehensive diagnostic measurements can be performed to locate the fault or impedance change using a Time Domain Reflectometer in transmission lines up to 2, 000' in length. A faulty or weak connector or splice could cause a costly and time consuming burn out.

* * All measurements can be stored and printed. Measurements that were once cost prohibitive, or were a last resort, can now be made routinely at a low cost.

* * Our engineer are very experienced in the installation and commissioning of transmitting and related equipment. We provide top quality work at affordable prices.
