1. Device Overview:

️· Product: HMC244G16
️· Type: GaAs MMIC (Monolithic Microwave Integrated Circuit) SP4T (Single-Pole, Four-Throw) Non-Reflective Switch.
️· Frequency Range: Designed for operation up to 4 GHz.

2. Electrical Characteristics:

️· Supply Voltage (Vdd): +5.0 Vdc ±10%
️· Bias Current (Idd): Typ. 3.0 mA, Max 7.0 mA
️· Control Voltages:
- Low state: 0 to +0.8 Vdc @ 5 uA
- High state: +2.0 to +5.0 Vdc @ 70 uA
️· Maximum Input Power: +20 dBm (0.05 - 0.5 GHz), +27 dBm (0.5 - 3.5 GHz)
️· Switching Configuration (Truth Table): Determines the RF path based on control inputs A and B (e.g., A=Low, B=Low routes signal to RF1).

3. Environmental & Physical Characteristics:

️· Operating Temperature: -40°C to +85°C
️· Storage Temperature: -65°C to +150°C
️· Package Material: Alumina-loaded Borosilicate Glass with Kovar leads.
️· Plating: Electrolytic Gold (50 microinches) over Electrolytic Nickel (75 microinches).
️· Grounding: Important to connect the package ground paddle to the PCB RF ground.

4. Key Features & Considerations:

️· Non-Reflective Design: Reduces signal reflections and improves performance.
️· 50 Ohm Matched: RF pins are DC-coupled and matched to 50 Ohms; blocking capacitors are required.
️· Evaluation Board Available: Hittite Microwave Corporation provides an evaluation circuit board.
