Product details
Overview
HMC241QS16ETR from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC SP4T non-reflective RF switch operating from DC to 3.5 GHz, featuring 0.5 dB insertion loss at 2 GHz, 45 dB isolation at 1 GHz, and integrated 2:4 TTL decoder for path selection with only two control lines. It is used in base station front-ends and wireless test equipment requiring low-loss, high-isolation signal routing under +5 V single-supply operation.
For engineers reviewing the HMC241QS16ETR datasheet, HMC241QS16ETR pinout, HMC241QS16ETR application, or HMC241QS16ETR equivalent, key selection criteria include its non-reflective architecture, TTL/CMOS-compatible control interface, DC–3.5 GHz bandwidth, 16-lead QSOP package, and +25 dBm input IP3 performance - all critical for RF front-end switching in portable wireless and CATV infrastructure.
Technical Context
This device implements a monolithic GaAs MMIC SP4T switch with internal termination for non-reflective operation across all off-states, enabling stable impedance matching in 50 Ω systems. Its integrated 2:4 TTL decoder reduces external logic complexity by mapping binary A/B inputs directly to RFC→RF1–RF4 paths without external gates.
The switch operates from a single +5.0 V ±10% supply, drawing only 4 mA typical current, and supports TTL/CMOS logic levels (0–0.8 V low, 2–5 V high) with 150 ns turn-on/off timing. Thermal resistance is specified at 210 °C/W for the insertion loss path, supporting operation from –40 °C to +85 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | DC to 3.5 GHz - supports broadband RF routing from baseband through UHF and low microwave bands. |
| Insertion Loss (2 GHz) | 0.5 dB typical - minimizes signal attenuation in active signal paths, preserving SNR in receiver chains. |
| Isolation (1 GHz) | 45 dB typical - ensures strong suppression of leakage between unselected RF ports, critical for MIMO and TDD duplexing. |
| Input IP3 | +44 dBm typical - enables handling of multi-tone signals without significant intermodulation distortion in shared front-ends. |
| Switching Time | 150 ns (tON/tOFF) - supports fast channel reconfiguration in time-division systems and automated test setups. |
| Supply Voltage | +5.0 V ±10% - compatible with standard digital logic rails, eliminating need for dedicated RF bias supplies. |
| Control Interface | TTL/CMOS-compatible A/B inputs - allows direct connection to FPGA GPIO or microcontroller outputs without level-shifting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SP4T RF switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Qorvo QM11036 | 0.6 dB IL @ 2 GHz, 35 dB isolation @ 2 GHz, +3.3 V supply, no integrated decoder. | Requires external logic for 4-path selection; optimized for 3.3 V systems with tighter layout constraints. | Choose when lower supply voltage and smaller 3×3 mm QFN package are prioritized over decoder integration and isolation. |
| Skyworks SKY13370-374LF | 0.7 dB IL @ 2.5 GHz, 38 dB isolation @ 2.5 GHz, +5 V supply, no integrated decoder, 16-pin QFN. | Lacks on-chip decoder; higher insertion loss but rated for +33 dBm P1dB, better for high-power front-ends. | Choose when higher power handling (>+27 dBm) is required and external decoding logic is acceptable. |

FAQ
What is the operating frequency range of the HMC241QS16ETR?
The HMC241QS16ETR operates from DC to 3.5 GHz, covering cellular bands (700 MHz–2.7 GHz), Wi-Fi (2.4/5 GHz), GPS L1/L2 (1.2–1.6 GHz), and CATV (54–1002 MHz). Its flat insertion loss and consistent isolation across this range make it suitable for multi-standard RF front-ends where wideband performance is mandatory.
Does the HMC241QS16ETR require external DC blocking capacitors?
Yes, the HMC241QS16ETR requires external DC blocking capacitors at RFC and all RF1–RF4 ports, as stated in the datasheet notes. This is necessary because the device lacks internal DC blocking, and applying DC bias to RF ports would disrupt matching and cause damage or performance degradation in 50 Ω systems.
What is the control logic configuration for path selection on the HMC241QS16ETR?
The HMC241QS16ETR uses a 2-bit TTL/CMOS-compatible control interface (pins A and B) with an integrated 2:4 decoder. Logic states LOW/LOW, HIGH/LOW, LOW/HIGH, and HIGH/HIGH select RFC-to-RF1, RF2, RF3, and RF4 paths respectively - eliminating need for external decoding logic and reducing control overhead.
What thermal considerations apply to the HMC241QS16ETR in continuous operation?
The HMC241QS16ETR has a thermal resistance of 210 °C/W for the insertion loss path and 250 °C/W for terminated paths. To ensure reliable operation at +85 °C ambient, all 15 ground pins must be soldered to a solid RF ground plane, and PCB layout must provide adequate copper area for heat spreading per the evaluation board guidelines.
Is the HMC241QS16ETR pin-compatible with the HMC241QS16 variant?
Yes, the HMC241QS16ETR is pin-compatible with the HMC241QS16, sharing identical 16-lead QSOP footprint, pinout, and electrical specifications. The "E" suffix denotes RoHS compliance with 100% matte tin plating and 260 °C peak reflow rating, while the base HMC241QS16 uses Sn/Pb plating and 235 °C reflow - both are mechanically and electrically interchangeable in existing designs.
