Blog Article
RF switches are an indispensable component in wireless communication equipment and play a key role in mobile phones, Bluetooth, WLAN, and L/S band digital phones. HX179-92-ST is a high-performance GaAs MMIC SPDT RF switch launched by ZHHXDZ. It is fully compatible with Skyworks' AS179-92LF in design and can be pin-to-pin compatible. This product has excellent performance and is suitable for application scenarios with high requirements for both cost and performance.
Product Features:
1. Superior Insertion Loss Performance
The HX179-92-ST provides extremely low insertion loss over a wide frequency band, significantly reducing signal attenuation:
• 0.05–1.0 GHz: typical value is only 0.25 dB
• 1.0–2.0 GHz: typical value is 0.30 dB
• 2.0–3.0 GHz: typical value is 0.35 dB
Low insertion loss can improve signal quality and enhance the overall performance of the device.
2. Excellent Isolation
The product provides up to 24–32 dB of isolation in the 0.05–3.0 GHz frequency band, effectively preventing signal interference and ensuring clarity between different channels.
3. Wide Control Voltage Range
The switch control voltage range of the HX179-92-ST is 1.8–5.3 V, supporting a variety of circuit design requirements and improving flexibility and compatibility.
4. High power handling capability
This product can handle input power up to +27 dBm, and performs well in scenarios that require high-power signal processing. In addition, when supporting a lower control voltage (1.8 V), its power capability can still reach +20 dBm.
5. Compact package form
The SOT-363 ultra-small package occupies a small PCB area and is convenient for high-density board design.
6. Reliability and wide temperature range
• Operating temperature range: -45°C to +85°C
• Storage temperature range: -55°C to +150°C
The HX179-92-ST can operate stably in both harsh industrial environments and consumer-grade devices.
Application Scenarios
1. Wireless Communication Equipment
The HX179-92-ST RF switch is ideal for wireless communication equipment, especially in scenarios where fast signal path switching is required, such as:
• WLAN (Wireless Local Area Network) equipment: used to select different antenna signal channels in routers or wireless access points.
• WLL (Wireless Local Loop): Optimizes signal selection and switching for wireless terminal equipment.
• Bluetooth module: Improves the stability of Bluetooth signals through low insertion loss switching.
2. L and S band digital mobile phones and wireless phones
For digital communication equipment (such as smartphones and wireless landlines) using the L (1–2 GHz) and S (2–4 GHz) bands, the HX179-92-ST provides:
• Excellent signal isolation to avoid signal interference.
• High power handling capability to meet the high signal power requirements in the equipment.
3. High-density circuit board design
The SOT-363 ultra-small package is particularly suitable for consumer electronic products that require compact space, such as:
• Smart home products (smart speakers, Wi-Fi sockets).
• Industrial IoT devices (need to maintain stable communication in harsh environments).
