Description and Introduction

GaAs MMIC SP3T NON-REFLECTIVE SWITCH, DC - 3.5 GHz The HMC245QS16 is a GaAs MMIC SP4T non-reflective switch manufactured by HITTITE (now part of Analog Devices). Here are its key specifications:

- **Frequency Range**: DC to 4 GHz  
- **Insertion Loss**: 1.2 dB typical at 2 GHz  
- **Isolation**: 45 dB typical at 2 GHz  
- **Input Power Handling**: 26 dBm (400 mW)  
- **Control Voltage**: 0/-5V (TTL compatible)  
- **Switching Speed**: 15 ns typical  
- **Package**: 16-lead QSOP (QS16)  
- **Operating Temperature**: -40°C to +85°C  

It is designed for applications requiring high isolation and fast switching, such as test equipment and wireless infrastructure.

Application Scenarios & Design Considerations

GaAs MMIC SP3T NON-REFLECTIVE SWITCH, DC - 3.5 GHz

Alternative Part Number

  • ADG901BRMZ --: Pin-compatible SPST RF switch in a similar QSOP package with comparable frequency range and low insertion loss; Analog Devices now owns the Hittite product line, so this is a close functional substitute.
  • PE4259 --: SPDT RF switch covering DC to 3 GHz with low insertion loss and high linearity, suitable as a functional replacement for the HMC245QS16 in most RF signal routing applications.
  • SKY13298-360LF --: GaAs SPDT RF switch in a compact package with similar frequency coverage and control interface, offering a viable alternative when the Hittite part is unavailable.
