QM-SP8T-DT7E DC-7GHz 8-Channel RF SP8T Switch Wideband Single Pole Eight Throw Microwave Switch
Description:
- Microwave switch, also known as RF switch, realizes the function of controlling the conversion of microwave signal channels. This module adopts the SP8T single pole eight throw mode to achieve the switching function of eight signals. The module is powered by a -5V single power supply, and is widely used in communication system equipment due to its low insertion loss, wide frequency band, and high isolation.
- The module adopts a CNC shell, which has excellent electromagnetic shielding performance.
Specification:
- Working frequency: DC-7GHz
- Model: QM-SP8T-DT7E
- Power supply: -5V
- Working mode: single pole 8 throw
- Typical insertion loss: ≤ 3.5dB at 2.4GHz (See the measured curve for details)
- Port isolation degree: ≥ 22dB at 2.4GHz (See the measured curve for details)
- Impedance: 50Ω
- Switching time: 150ns
- Maximum input power: +26dBm
- Input/output interface: SMA (external screw and internal hole)
- Module size: 72 x 48 x 12mm (excluding connectors length)
- With installation and positioning holes
- Control method:
A: 1, B: 1 C: 1 RFC output to RF1;
A: 0, B: 1 C: 1 RFC output to RF2;
A: 1, B: 0 C: 1 RFC output to RF3;
A: 0, B: 0 C: 1 RFC output to RF4;
A: 1, B: 1 C: 0 RFC output to RF5;
A: 0, B: 1 C: 0 RFC output to RF6;
A: 1, B: 0 C: 0 RFC output to RF7;
A: 0, B: 0 C: 0 RFC output to RF8.
- Note: In the control rule, 1 is a high level: -4.2V to -5V; and 0 is a low level: -2.5V to 0V or directly grounded.
