These alternatives offer similar functionalities in RF switching applications. Always check the datasheets for specific performance metrics and compatibility with your design requirements.

The HMC347A is a broadband 6-bit GaAs IC digital attenuator. It provides precise attenuation from 0.5 to 31.5 dB in 0.5 dB steps with a low insertion loss. Operating in the DC to 20 GHz range, it features monotonicity over its entire attenuation range, making it suitable for a wide variety of applications, including those in telecommunications, military, and test equipment. The attenuator has a high linearity with excellent input third-order intercept point (IP3) and high power handling capability. It is designed to operate on a single +3V/+5V supply and provides a parallel control interface. The compact design is available in a RoHS compliant 24-lead 4x4 mm QFN SMT package, ensuring ease of integration into various systems.

The HMC347A is a broadband SPDT (Single-Pole Double-Throw) switch used in RF and microwave applications. It typically comes in a 6-lead SOT-26 package. The primary function of the HMC347A is to route RF signals between its input and one of the two outputs, with high isolation and low insertion loss.
Key features include:
- Frequency range: DC to 20 GHz
- Low insertion loss: Typically 1.5 dB
- High isolation: Typically 37 dB
- Fast switching speed: Approximately 6 ns
The pin configuration for the HMC347A:
1. RF1 (Output 1)
2. GND (Ground)
3. RF2 (Output 2)
4. Vctl (Control Voltage)
5. RF COM (Common RF Input/Output)
6. GND (Ground)
The control voltage (Vctl) determines the switch position, toggling the RF COM between RF1 and RF2. The HMC347A is widely used in test equipment, communication systems, and other RF applications due to its wide frequency range and reliable performance.
