Product details
Overview
HMC596LP4ETR from Analog Devices (formerly Hittite Microwave) is a surface-mount 4×2 RF switch matrix IC designed for satellite LNBs and multiswitches. It operates from 200 MHz to 3.0 GHz, delivers ≤7.5 dB insertion loss (typ. 7 dB at 2.15–3.0 GHz), ≥40 dB isolation (min. 37 dB across band), and supports dual independent output selection with integrated CMOS-compatible 4-bit decoder. It functions in both 50 Ω and 75 Ω systems.
For engineers reviewing the HMC596LP4ETR datasheet, HMC596LP4ETR pinout, HMC596LP4ETR application, or HMC596LP4ETR equivalent, key selection criteria include its bi-directional 4-input/2-output architecture, +5 V single-supply operation, 24-lead 4×4 mm QFN package, and verified performance in DBS LNB front-end switching and CATV multiswitch signal routing.
Technical Context
The HMC596LP4ETR implements a fully decoded 4×2 RF switch matrix using internal CMOS logic to drive four independent RF paths (VL, HL, VH, HH) to either OP1 or OP2. Its control interface uses four logic inputs (HV1, HV2, Tone1, Tone2) with TTL/CMOS-compatible thresholds (0–0.8 V low, +2–+5 V high) and no external biasing required.
It is DC-coupled on all six RF ports (four inputs + two outputs), mandating external 330 pF DC-blocking capacitors per port; Vdd requires a 1000 pF decoupling capacitor. The device exhibits stable RF performance from –40 °C to +85 °C, with typical input IP3 of +27 dBm and P1dB of +22 dBm across 200–3000 MHz.
Key Specifications

Pinout & Package
Package: 24-lead, leadless 4×4 mm QFN with exposed thermal paddle (MSL1, RoHS-compliant matte Sn finish). Requires soldering of all ground leads and paddle to PCB RF ground per Hittite layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1,2,4–6,13–15,17,18) | RF and DC Ground Reference | Must be connected to low-inductance PCB ground plane; exposed paddle is integral part of RF return path. |
| HL, VL, VH, HH (Pins 3,16,19,24) | RF Input Ports | Four bidirectional RF inputs; each requires external 330 pF DC-blocking capacitor for AC coupling. |
| OP1, OP2 (Pins 7,12) | RF Output Ports | Two independent RF outputs; support simultaneous or identical input selection; DC-coupled, require blocking caps. |
| HV1, HV2, Tone1, Tone2 (Pins 11,9,10,8) | Digital Control Inputs | CMOS-compatible logic interface (0–0.8 V low, +2–+5 V high); no pull-up/down needed; drives internal decoder. |
| Vdd (Pin 21) | Power Supply | +5 V ±10% supply; requires 1000 pF 0603 decoupling capacitor close to pin. |
| N/C (Pins 20,22,23) | No Connection | Not internally bonded; must remain unconnected on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 4-bit CMOS decoder | Eliminates need for external logic or FPGA GPIO resources-reduces BOM count and layout area in LNB modules. |
| Bidirectional RF path capability | Enables flexible signal routing (e.g., OP1 as input, VL as output) without redesign-supports reuse in transceiver front-ends. |
| 50 Ω / 75 Ω system compatibility | Validated performance in both impedance domains-simplifies adoption across satellite (75 Ω) and telecom (50 Ω) platforms. |
| Low power consumption | Typ. 0.2 mA Idd at +5 V-enables integration into power-constrained outdoor LNB units with minimal thermal impact. |
| High linearity (P1dB = +22 dBm) | Preserves signal integrity in multi-carrier CATV and DOCSIS 3.1 environments where compression must be avoided. |
Applications
| Direct Broadcast Satellite (DBS) LNBs | Cable Modem / CATV Multiswitches |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF switch matrix applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC596LP4 | Sn/Pb lead finish, MSL1, peak reflow 235 °C; identical electrical specs and pinout. | Non-RoHS; suitable only for legacy or exempted industrial assemblies. | Select HMC596LP4ETR for new designs requiring RoHS compliance and 260 °C reflow compatibility. |
| Qorvo QM11024 | 4×2 SP4T switch, 50–6000 MHz, +3.3 V supply, higher IL (8.5 dB @ 3 GHz), smaller 3×3 mm QFN. | Broader bandwidth but lower isolation (32 dB @ 2.5 GHz); optimized for 5G FR1 front-ends vs. satellite LNBs. | Choose QM11024 only if 3.3 V supply and extended frequency coverage outweigh isolation and LNB-specific validation requirements. |
Compared with HMC596LP4 (Sn/Pb) and QM11024 (3.3 V, wider band), the HMC596LP4ETR offers RoHS-compliant packaging, proven 50–75 Ω interoperability, and superior isolation in the 0.2–3.0 GHz satellite band-making it the preferred choice for DBS LNB and multiswitch production.

FAQ
What is the operating frequency range of the HMC596LP4ETR?
The HMC596LP4ETR operates from 200 MHz to 3.0 GHz, with full electrical specifications validated across this band in a 50 Ω system. Performance data-including insertion loss, isolation, and return loss-is provided in 3 frequency sub-bands (200–950 MHz, 950–2150 MHz, 2150–3000 MHz) and confirmed for use in both 50 Ω and 75 Ω applications such as DBS LNBs and CATV multiswitches.
Does the HMC596LP4ETR require external DC blocking capacitors?
Yes, the HMC596LP4ETR requires external DC blocking capacitors on all six RF ports (VL, HL, VH, HH, OP1, OP2). The datasheet specifies 330 pF, 0402-size capacitors for all RF ports, selected based on the lowest operating frequency. This is mandatory because all RF pins are DC-coupled, and failure to implement blocking will disrupt biasing and impair RF performance.
What is the supply voltage requirement for the HMC596LP4ETR?
The HMC596LP4ETR requires a single +5.0 V DC supply with ±10% tolerance (i.e., +4.5 V to +5.5 V). Typical supply current is 0.2 mA, with a maximum of 0.4 mA at +25 °C. A 1000 pF, 0603-size decoupling capacitor is recommended directly at the Vdd pin (Pin 21) to ensure stable operation under RF switching transients.
Can the HMC596LP4ETR be used in a 75 Ω system?
Yes, the HMC596LP4ETR is explicitly characterized and qualified for use in both 50 Ω and 75 Ω systems. While all published RF specifications (insertion loss, isolation, return loss) were measured in a 50 Ω test setup, the device's architecture and internal matching support stable operation in 75 Ω environments such as DBS LNBs and broadcast multiswitches without modification.
What is the thermal resistance and maximum junction temperature of the HMC596LP4ETR?
The HMC596LP4ETR has a thermal resistance (θJA) of 325 °C/W and a maximum channel temperature rating of 150 °C. Its operating temperature range is –40 °C to +85 °C. To maintain reliability, the exposed paddle must be soldered to a thermally robust PCB ground plane with multiple vias, per the Hittite land pattern recommendation.
