The HMC260LC3BTR from Analog Devices Inc. is a state-of-the-art MMIC SPDT (Single Pole Double Throw) non-reflective switch, designed to operate within the frequency range of DC to 40 GHz. This high-performance switch is an ideal choice for a wide range of applications, including test instrumentation, microwave radio, and military radar systems, thanks to its broad frequency range and high isolation characteristics.

Housed in a compact 3x3 mm SMT package, the HMC260LC3BTR is part of the Hittite Microwave product line from Analog Devices and is specifically engineered for space-constrained applications requiring a small footprint without sacrificing performance. It is fabricated using a GaAs MESFET process which provides full passivation for increased performance and reliability.

The HMC260LC3BTR features exceptional RF performance with an insertion loss of less than 2.5 dB and high isolation of up to 42 dB, ensuring minimal signal leakage between ports. The switch also boasts a high input IP3 of 50 dBm, providing excellent linearity for complex signal environments. Additionally, it operates over a wide supply voltage range from -5V to +5V, offering design flexibility.

The switch is controlled via two control voltage inputs (0/-5V), which are CMOS/TTL compatible, making it easy to integrate into digital systems. The non-reflective design of the switch ensures that any RF signal terminated into the switch in the "OFF" state is absorbed, rather than reflected back, which is critical for maintaining signal integrity in sensitive RF chains.

Key features of the HMC260LC3BTR include:

• Frequency Range: DC - 40 GHz
• Non-Reflective Design
• High Isolation: Up to 42 dB
• Low Insertion Loss: < 2.5 dB
• High Input IP3: 50 dBm
• Control Voltage: 0/-5V, CMOS/TTL Compatible
• Compact 3x3 mm SMT Package

The HMC260LC3BTR is ready to meet the demanding requirements of high-frequency signal routing and is an essential component for designers looking to maximize performance in their RF and microwave systems.
