Analog Devices Inc. HMC241ATCPZ-EP-R7

Overview

HMC241ATCPZ-EP-R7 from Analog Devices is a GaAs-based nonreflective SP4T RF switch operating from 100 MHz to 4 GHz, delivering 0.7 dB insertion loss and 43 dB isolation at 2 GHz, with integrated 2-to-4 TTL decoder for logic-controlled RF path selection in cellular infrastructure and test equipment.

For engineers reviewing the HMC241ATCPZ-EP-R7 datasheet, HMC241ATCPZ-EP-R7 pinout, HMC241ATCPZ-EP-R7 application, or HMC241ATCPZ-EP-R7 equivalent, key selection criteria include broadband isolation performance across military temperature range (−55°C to +125°C), 3–5 V single-supply operation, and LFCSP package compatibility with high-density RF layouts.

Technical Context

The HMC241ATCPZ-EP-R7 implements a monolithic GaAs SP4T architecture with on-chip 50 Ω terminations for all isolated ports, enabling true nonreflective switching without external matching. Its integrated binary 2-to-4 line decoder accepts TTL-compatible CTRLA/CTRLB inputs to select one of four RF paths (RF1–RF4) from the common RFC port.

Designed for enhanced product qualification, the device supports defense/aerospace use via controlled manufacturing baseline, single assembly/test site, and AQEC compliance. It maintains specified RF performance across −55°C to +125°C case temperature, with thermal resistance θJC = 144°C/W (through path) and ESD rating of 250 V HBM (Class 1A).

FAQ

What is the operating temperature range of the HMC241ATCPZ-EP-R7?

The HMC241ATCPZ-EP-R7 is rated for continuous operation from −55°C to +125°C case temperature, validated per AQEC standards for defense and aerospace applications. This extended range exceeds commercial-grade alternatives and ensures reliability in avionics, radar, and outdoor telecom enclosures where ambient extremes occur. The HMC241ATCPZ-EP-R7 maintains full RF specifications-including 0.7 dB insertion loss and 43 dB isolation at 2 GHz-across this entire range.

Does the HMC241ATCPZ-EP-R7 require external termination resistors?

No, the HMC241ATCPZ-EP-R7 features on-chip 50 Ω terminations for all isolated RF ports (RF1–RF4 when not selected), making it a true nonreflective switch. This eliminates the need for external 50 Ω resistors or matching networks, reducing bill-of-materials count and PCB area. The HMC241ATCPZ-EP-R7 achieves >12 dB return loss on off-state ports across 100 MHz–4 GHz without external components.

What logic levels are compatible with the CTRLA and CTRLB pins of the HMC241ATCPZ-EP-R7?

The CTRLA and CTRLB pins accept TTL-compatible logic: low input ≤ 0.8 V and high input ≥ 2.0 V (at VDD = 3 V) or ≥ 2.0 V (at VDD = 5 V). These inputs drive an integrated 2-to-4 decoder, so only two control lines are needed to select among four RF paths. The HMC241ATCPZ-EP-R7 draws < 40 µA per control input, enabling direct interfacing with microcontrollers and FPGAs without level-shifting circuitry.

Can the HMC241ATCPZ-EP-R7 be used with 50 Ω DC-coupled RF traces?

Yes-the HMC241ATCPZ-EP-R7 RF ports (RFC, RF1–RF4) are fully DC-coupled and internally matched to 50 Ω. However, a dc blocking capacitor must be placed in series with each RF port to prevent DC bias disruption in connected circuits. The HMC241ATCPZ-EP-R7's nonreflective architecture ensures stable 50 Ω impedance regardless of switch state, supporting seamless integration into DC-coupled RF signal chains.

What is the maximum RF input power the HMC241ATCPZ-EP-R7 can handle in terminated-path mode at 5 V supply?

At VDD = 5 V, the HMC241ATCPZ-EP-R7 supports up to 23.5 dBm RF input power on terminated paths (i.e., when the selected RF port is not RFC) at TCASE = 85°C, per Absolute Maximum Ratings. This rating applies to continuous-wave signals and accounts for thermal derating; the HMC241ATCPZ-EP-R7 also supports hot-switching up to 22.5 dBm under the same conditions. Exceeding these limits risks permanent damage to internal GaAs FETs.
