External Amplifier 802.11-b 200mW

REF: AN071
Specifications
  • Bi-directional amplifier that operates in the 2.4GHz band, ideal for applications based on 802.11-b wireless network.
  • Ideal to compensate the loss of power radiated by long distances of cables, to have more range, or other uses.
  • Manufactured in metal and totally airtight to be installed outdoors and with protection from electric shocks caused by external elements.
  • It is basically composed of three elements: the DC injector (or DC-Injector), the power supply and the outdoor amplifier.
  • The DC injector is installed inside and unifies in the same cable that goes to the amplifier, the signal to be radiated (from the network equipment or similar) and the power supply (from the 6VDC power supply).

Bi-directional amplifier that operates in the 2.4GHz band, ideal for applications based on 802.11-b wireless network. Ideal to compensate the loss of power radiated by long distances of cables, to have more range, or other uses. Manufactured in metal and totally airtight to be installed outdoors and with protection from electric shocks caused by external elements. It is basically composed of three elements: the DC injector (or DC-Injector), the power supply and the outdoor amplifier. The DC injector is installed inside and unifies in the same cable that goes to the amplifier, the signal to be radiated (from the network equipment or similar) and the power supply (from the 6VDC power supply). The amplifier has an input from the DC injector and an output that goes to the antenna, and it amplifies thesignals sent and received, apart from separating the data signals from the electric signals, from which it is fed. Both the amplifier and the injector have N-Female connectors (50 Ohm). Transmission gain of 27dB (max adjusted automatically). Output power of 200 mW. Reception gain of 15dB (typical). Compatible with wireless networks that comply with the 802.11-b standard. Amplifier size of 115 x 65 x 48 mm. T7.8 x 5.6 x 2.9 cm injector size. Supplied with rSMA-Male to N-Male hose to connect to the injector to the access point. It also includes hardware to fix the external amplifier to the own mast.

Impedance

Impedance (Z) is the total opposition that a circuit offers to alternating current (AC) flow when a specific voltage is applied.

Unlike simple resistance, impedance is a complex quantity comprising resistance (the real part) and reactance (the imaginary part, representing inductive or capacitive effects). In the frequency domain, impedance is represented as a phasor, accounting for both magnitude and phase shift between voltage and current. In DC circuits, impedance reduces to pure resistance with zero phase angle.

UnitOhm (Ω)

Impedance management is critical in high-speed hardware design and signal integrity. In modern PCB manufacturing, controlled impedance ensures that high-frequency signals reach their destination without reflections, which is vital for PCIe or DDR5 performance.

Complex Domain Analysis

Mathematical modeling of impedance using the j-operator allows engineers to optimize filter performance and resonance characteristics in electronic systems.

Key Advantages

  • Maximum power transfer through impedance matching.
  • Minimized signal reflections in high-frequency transmission lines.
  • Improved electromagnetic compatibility (EMC).

Note: Impedance is the cornerstone of modern AC circuit theory and high-frequency design.
