Product details
Overview
HMC244G16 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC SP4T non-reflective RF switch in a hermetic 16-lead glass/metal package, operating from DC to 4 GHz. It delivers 0.7 dB insertion loss at 3 GHz, 30–50 dB isolation, and integrates a 2:4 TTL/CMOS decoder for path selection using only two control lines and +5 V bias - enabling compact front-end switching in wideband transceivers.
For engineers reviewing the HMC244G16 datasheet, HMC244G16 pinout, HMC244G16 application, or HMC244G16 equivalent, key selection criteria include its non-reflective architecture, DC–4 GHz bandwidth, integrated decoder reducing control complexity, and hermetic SMT packaging for high-reliability RF systems.
Technical Context
The HMC244G16 implements a monolithic GaAs MMIC design with four RF paths (RF1–RF4) routed to a common RFC port via PIN diode-based switching elements. Its non-reflective topology terminates all off-state ports into 50 Ω, minimizing signal reflection and enabling use in transmit/receive T/R modules without external termination.
Control logic uses a built-in 2:4 TTL/CMOS decoder driven by dual digital inputs (A, B), eliminating external decoding circuitry. Bias is supplied via a single +5.0 Vdc ±10% rail (Vdd), drawing only 3.0 mA typical current, supporting low-power RF subsystems across industrial and aerospace temperature ranges (−40°C to +85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | DC to 4.0 GHz - supports broadband operation from baseband through L/S-band, including cellular, radar, and test instrumentation bands. |
| Insertion Loss | 0.7 dB typ. @ 3 GHz - enables minimal signal attenuation in active antenna or diversity switching paths. |
| Isolation | 35 dB typ. @ 3 GHz - ensures strong channel separation in multi-path RF routing, critical for TDD/FDD duplexing. |
| Input IP3 | 43 dBm typ. @ 0.5–3.0 GHz - maintains linearity under multi-tone conditions in receiver front-ends and signal analyzers. |
| Switching Speed | tON/tOFF = 150 ns max - supports fast frequency hopping and agile waveform switching in ECM and military radios. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SP4T RF switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC547LP3E | DC–6 GHz, 0.8 dB IL @ 4 GHz, 32 dB isolation @ 4 GHz, 16-pin QFN (non-hermetic) | Higher frequency coverage but lower isolation above 3 GHz; plastic package unsuitable for space/military hermetic requirements. | Select when extended bandwidth to 6 GHz is needed and environmental sealing is not mandatory. |
| Qorvo QM11036 | DC–4.2 GHz, 0.9 dB IL @ 3.5 GHz, 38 dB isolation @ 3 GHz, 16-pin laminate SMT, +5 V bias | Similar RF specs but uses GaN-on-SiC process; higher P1dB (+32 dBm) but no integrated decoder - requires external logic. | Select when higher power handling is prioritized over control simplicity and decoder integration. |
Compared with HMC244G16, HMC547LP3E offers wider bandwidth but lacks hermeticity and decoder integration, while QM11036 trades control-line reduction for higher power capability - making HMC244G16 optimal for size-constrained, decoder-sensitive, high-reliability RF routing.

FAQ
What is the operating frequency range of the HMC244G16?
The HMC244G16 operates from DC to 4.0 GHz, with specified performance across multiple bands: insertion loss is 0.7 dB typical at 3 GHz, isolation reaches 35 dB at 3 GHz, and return loss exceeds 18 dB up to 3.5 GHz. This makes the HMC244G16 suitable for L-band radar, S-band satellite comms, and multi-standard wireless infrastructure.
Does the HMC244G16 require external termination resistors?
No, the HMC244G16 does not require external termination resistors because it features a non-reflective SP4T architecture that internally terminates all off-state RF ports into 50 Ω. This eliminates signal reflections and simplifies PCB layout - a key advantage over reflective switches like the HMC349A, where external 50 Ω resistors are mandatory.
What control voltage levels are compatible with the HMC244G16?
The HMC244G16 accepts TTL/CMOS-compatible control voltages: logic low is 0–0.8 Vdc (5 µA typical sink), and logic high is +2.0–+5.0 Vdc (70 µA typical source). These levels align directly with standard FPGA and microcontroller GPIO outputs, enabling seamless integration without level-shifting circuitry in the HMC244G16 control interface.
Is the HMC244G16 pin-compatible with other Hittite SP4T switches?
No, the HMC244G16 is not pin-compatible with other Hittite SP4T switches such as the HMC349A or HMC547LP3E - its 16-lead hermetic package has unique pin assignments, including dedicated ground paddle connections and integrated decoder inputs (A/B). Layout reuse requires verification against the HMC244G16 outline drawing and pin descriptions.
What is the maximum RF input power the HMC244G16 can handle?
The HMC244G16 supports +27 dBm maximum input power from 0.5–3.5 GHz and +20 dBm from 0.05–0.5 GHz, per absolute maximum ratings. At typical operating conditions (Vdd = +5 Vdc), its 1 dB compression point is +25 dBm at 0.5–4.0 GHz, ensuring linear operation in high-dynamic-range receiver front-ends and moderate-power transmitter paths.
