The HMC226 is a high performance, low cost SPDT switch from Hittite Corporation. It is suitable for 450MHz, 900MHz and 1.8-2.0GHz applications of transmit and receive. The switch has a low insertion loss of 0.5-0.8dB and a high input compression point (P1dB) and third order intercept point (IP3). The switch is packaged in SOT26 and is powered by +3V. The input current is low, and it is compatible with CMOS and most TTL logic circuits.
The HMC226 is a 6‑lead SOT26 GaAs MMIC SPDT switch designed for transmit‑receive applications that require very low distortion at high signal power levels. It operates from DC to 2.0 GHz and is suited for 450 MHz, 900 MHz, and 1.8‑2.0 GHz bands, offering typical insertion loss of 0.6 dB and high P1dB and IP3 performance.
Key specifications include a control voltage range of 0/+3 V to 0/+8 V, typical isolation of 23 dB, return loss of 23 dB, and a maximum input power of +27 dBm. The device supports CMOS and TTL logic control, requires DC blocking capacitors on RF ports, and is intended for use with proper 50 Ω RF board design.
