Product details
Overview
HMC241LP3E from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC SP4T non-reflective RF switch operating from DC to 4 GHz, featuring 0.7 dB insertion loss and 43 dB isolation at 2 GHz, with integrated 2:4 TTL decoder and single +5 V supply. It serves as a signal path selector in multi-band front-end modules for wireless infrastructure.
For engineers reviewing the HMC241LP3E datasheet, HMC241LP3E pinout, HMC241LP3E application, or HMC241LP3E equivalent, key selection criteria include its non-reflective architecture, TTL/CMOS-compatible control interface, 3×3 mm leadless RoHS-compliant package, and DC–4 GHz bandwidth with verified 26 dBm P1dB and 45 dBm IP3 performance.
Technical Context
The HMC241LP3E implements a monolithic GaAs MMIC design with on-die termination for all off-state ports, enabling true non-reflective operation across DC–4 GHz. Its integrated 2:4 TTL decoder reduces external logic count by mapping two digital inputs (A/B) to four RF paths (RF1–RF4), eliminating need for discrete decoding circuitry.
It operates with single +5 V ±10% supply and supports TTL/CMOS logic levels: low control (0–0.8 V) and high control (+2.0–+5.0 V). DC blocking capacitors are required at RFC and RF1–RF4 ports per datasheet specification, and all ground pins-including exposed paddle-must connect directly to PCB RF ground.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | DC to 4 GHz - supports full-band operation from baseband up through WiMAX and WLAN bands without re-tuning. |
| Insertion Loss | 0.7 dB @ 2 GHz - ensures minimal signal attenuation in selected path, preserving SNR in receiver chains. |
| Isolation | 43 dB @ 2 GHz - prevents crosstalk between unselected RF ports, critical for TDD/FDD duplexing integrity. |
| P1dB | 26 dBm @ 0.3–4 GHz - enables handling of moderate-power transmit signals without compression in repeater applications. |
| IP3 | 45 dBm - provides robust linearity for two-tone +7 dBm inputs, reducing intermodulation distortion in dense spectral environments. |
| Switching Time | 100 ns tON/tOFF - supports fast channel switching in time-division systems such as LTE TDD base stations. |
| Supply Voltage | +5 V ±10% - simplifies biasing with standard LDOs and avoids dual-rail supplies. |
Pinout & Package
Package: 3×3 mm, 16-pin leadless surface-mount package (RoHS-compliant, matte tin plating, MSL1, max reflow 260 °C); exposed ground paddle requires solder connection to PCB RF ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12, 15 | RF4, RF3, RF2, RF1, RFC | DC-coupled 50 Ω RF ports; require external DC blocking capacitors per datasheet note. |
| 2, 3, 10, 11, 13 | N/C | No-connect pins; must be tied to PCB RF ground to maximize isolation and thermal dissipation. |
| 5, 14, 16 | GND | Ground terminals including exposed paddle; mandatory low-inductance connection to solid RF ground plane. |
| 6 | Vdd | +5 V ±10% supply input; decoupling capacitor required near pin per RF layout guidelines. |
| 7 | B | TTL/CMOS control input (B bit); referenced to ground, drives internal 2:4 decoder. |
| 8 | A | TTL/CMOS control input (A bit); paired with B to select RFC→RF1–RF4 per truth table. |
Key Features
| Feature | Design Value |
|---|---|
| Non-reflective SP4T architecture | Terminated off-state ports prevent signal reflection, enabling stable impedance matching in cascaded RF stages. |
| Integrated 2:4 TTL decoder | Reduces control interface to only two logic lines (A/B), eliminating external decoder ICs and saving board space. |
| TTL/CMOS-compatible control | Accepts 0–0.8 V low and +2.0–+5.0 V high logic thresholds, allowing direct interfacing with FPGA/GPIO without level shifters. |
| Single +5 V supply | Eliminates need for negative or auxiliary bias rails, simplifying power delivery in compact RF modules. |
| RoHS-compliant 3×3 mm package | Enables high-density RF layout with standardized reflow profile (260 °C peak) and improved thermal resistance (200 °C/W on insertion path). |
Applications
| Base Station Front-End | WiMAX/WLAN Access Point |

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 | Wider bandwidth (DC–6 GHz), higher P1dB (+30 dBm), but requires dual supply (Vdd = +3.3 V, Vctl = +1.8 V). | Better suited for 5G FR1 front-ends needing >4 GHz coverage; incompatible with single +5 V systems. | Select QM11036 only if bandwidth extension beyond 4 GHz and higher power handling are required and dual-supply design is acceptable. |
| Skyworks SKY13370-378LF | Lower isolation (35 dB @ 2 GHz), smaller 2×2 mm package, no integrated decoder - requires external logic. | Targeted at space-constrained IoT modules where size outweighs isolation needs; lacks decoder integration. | Choose SKY13370-378LF when PCB area is critical and system-level logic already exists to drive four independent control lines. |
Compared with QM11036 and SKY13370-378LF, the HMC241LP3E uniquely balances DC–4 GHz operation, integrated TTL decoder, single +5 V supply, and 43 dB isolation - making it optimal for cost-sensitive, medium-power wireless infrastructure where layout simplicity and proven reliability are prioritized over extreme bandwidth or miniaturization.

FAQ
What is the operating temperature range for the HMC241LP3E?
The HMC241LP3E is specified for operation from –40 °C to +85 °C ambient temperature. This range supports deployment in outdoor base station enclosures and indoor enterprise access points without active thermal management. The device's thermal resistance is 200 °C/W on the insertion loss path, enabling reliable performance under sustained RF power conditions within this envelope. Derating is not required at the upper limit when PCB ground paddle is properly soldered.
Does the HMC241LP3E require external DC blocking capacitors?
Yes, the HMC241LP3E requires external DC blocking capacitors at RFC and RF1–RF4 ports, as explicitly stated in the datasheet Pin Descriptions section. These capacitors isolate DC bias from adjacent RF stages while maintaining 50 Ω impedance across the operating band. Typical values used on evaluation boards are 100 pF (0402) for RF paths and 10 k pF (0603) for RFC, placed as close as possible to the package pins.
Is the HMC241LP3E pin-compatible with the HMC241LP3?
Yes, the HMC241LP3E is pin-compatible with the HMC241LP3. Both share identical 16-pin 3×3 mm footprint, pin functions, and electrical specifications. The sole difference is RoHS compliance: HMC241LP3E uses 100% matte tin plating and supports 260 °C reflow, whereas HMC241LP3 uses Sn/Pb plating rated for 235 °C. No PCB layout change is needed when migrating from HMC241LP3 to HMC241LP3E.
What logic levels does the HMC241LP3E accept on control pins A and B?
The HMC241LP3E accepts standard TTL/CMOS logic levels on pins A and B: low state is defined as 0–0.8 Vdc at ≤5 µA typical current draw, and high state is +2.0–+5.0 Vdc at ≤70 µA typical. This allows direct interfacing with microcontrollers, FPGAs, and logic families without level-shifting circuitry. The internal 2:4 decoder interprets the A/B combination to route RFC to RF1–RF4 per the documented truth table.
Can the HMC241LP3E be used in reflective (series-shunt) configurations?
No, the HMC241LP3E is a non-reflective SP4T switch with on-die 50 Ω terminations for all off-state ports. It is not designed for reflective operation. Attempting to use it in a series-shunt configuration would violate its internal architecture and degrade isolation, return loss, and power handling. The datasheet mandates DC blocking capacitors and specifies non-reflective behavior - confirming its intended use as a terminated, absorptive switch.
