Product details
Overview
HMC183QS24E from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC SP8T non-reflective RF switch operating from DC to 2 GHz, featuring 0.8 dB typical insertion loss at 1 GHz, integrated 3:8 decoder logic, and -5 V negative control voltage compatibility. It serves as an antenna diversity or switched filter bank selector in basestation infrastructure with terminated outputs in OFF state.
For engineers reviewing the HMC183QS24E datasheet, HMC183QS24E pinout, HMC183QS24E application, or HMC183QS24E equivalent, key selection criteria include its non-reflective architecture, 24-lead QSOP package footprint compatibility with SOIC-14 area, -40°C to +85°C operating temperature range, and 35 ns RF rise/fall time for high-speed channel switching.
Technical Context
The HMC183QS24E implements a monolithic GaAs MMIC topology with on-die 3:8 decoder, reducing external control lines from 16 to 3 for SP8T path selection. Its non-reflective design terminates all eight RF outputs when deselected, maintaining system impedance integrity across DC–2 GHz.
It operates under dual-rail negative bias: Vee = -5 V ±10% supplies the switch core and decoder, while control inputs (A/B/C) accept logic levels referenced to Vee (–5 V to –4.2 V for HIGH, 0 to –3 V for LOW), enabling direct interface with negative-voltage logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | DC to 2.0 GHz - supports full-band cellular infrastructure including GSM, UMTS, LTE low/mid-bands. |
| Insertion Loss (1 GHz) | 0.8 dB typ - minimizes signal attenuation in active RF paths, preserving receiver sensitivity and transmitter EIRP. |
| Isolation (1 GHz) | 32 dB min - prevents crosstalk between selected and deselected antenna or filter paths. |
| Return Loss (RFC, 1 GHz) | 10 dB min - ensures stable 50 Ω match at common RF port under all switching states. |
| Switching Speed | tRISE/tFALL = 35 ns - enables <28 MHz channel update rate for dynamic antenna tuning applications. |
| Control Interface | 3-bit negative logic (A/B/C) - eliminates need for level shifters when paired with -5 V logic drivers. |
| Supply Voltage | Vee = -5.0 V ±10% - single negative rail simplifies biasing versus dual-supply alternatives. |
Pinout & Package
Package: 24-lead QSOP (Quad Small Outline Package), RoHS-compliant, matte tin-plated copper alloy leadframe, MSL1 rating, 260 °C peak reflow. Footprint occupies same PCB area as 14-lead SOIC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Vee | Negative supply rail | Single -5 V supply for switch core and integrated decoder; all ground pins must connect to PCB RF ground plane. |
| A, B, C | Decoder address inputs | 3-bit negative logic control lines selecting one of eight RF paths; HIGH = -5 to -4.2 V, LOW = 0 to -3 V. |
| RFC | Common RF input | 50 Ω matched input port accepting signal routed to selected RF1–RF8 output. |
| RF1–RF8 | RF output terminals | Eight individually terminated 50 Ω outputs; only one active at a time, others internally 50 Ω-terminated. |
| GND (Leads 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24) | RF and substrate ground | All 24 leads include ground connections; package bottom and all GND leads require low-inductance solder to PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Non-reflective SP8T architecture | Internally terminates all unselected RF outputs to 50 Ω, preventing impedance discontinuities during switching transitions. |
| Integrated 3:8 decoder | Reduces required control lines from 16 to 3, eliminating external decoding logic and saving board space and power. |
| QSOP-24 package | Provides 8 RF I/Os plus control and supply in compact 7.6 × 12.8 mm body-same PCB area as SOIC-14. |
| -5 V single-rail operation | Eliminates need for positive/negative dual supplies; compatible with legacy -5 V logic and bias systems. |
| DC–2 GHz bandwidth | Covers all major cellular bands (700 MHz, 850 MHz, 900 MHz, 1800 MHz, 1900 MHz, 2100 MHz, 2600 MHz). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SP8T RF switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC253QS24 | TTL/positive bias version (Vdd = +5 V); no integrated decoder; requires 8 separate control lines. | Suitable where existing +5 V logic infrastructure exists and board space allows external decoding. | Select HMC253QS24 only if system lacks -5 V rail and can accommodate additional control routing and decoding logic. |
| Qorvo QM11036 | SP8T reflective switch (no internal terminations); 0.7 dB IL at 2 GHz; 3.3 V CMOS-compatible control. | Requires external 50 Ω terminations on unused RF ports; better suited for cost-sensitive consumer designs with relaxed VSWR requirements. | Choose QM11036 when minimizing bill-of-materials cost is critical and system-level matching networks compensate for reflective OFF-state behavior. |
Compared with HMC253QS24 and QM11036, the HMC183QS24E uniquely combines non-reflective operation, integrated 3:8 decoding, and -5 V single-rail bias in QSOP-24-enabling simpler, more robust RF path switching in infrastructure-grade basestation designs without external termination or decoding components.

FAQ
What is the maximum operating frequency of the HMC183QS24E?
The HMC183QS24E is specified for continuous operation from DC to 2.0 GHz. Insertion loss remains ≤1.8 dB and isolation ≥26 dB across this full band, making it suitable for all major cellular standards including LTE Bands 12/13/17 (700 MHz), Band 5 (850 MHz), Band 8 (900 MHz), Band 3 (1800 MHz), Band 1 (2100 MHz), and Band 7 (2600 MHz). Performance is characterized at +25°C with -5 V bias.
Does the HMC183QS24E require external termination resistors?
No. The HMC183QS24E is a non-reflective SP8T switch with all eight RF outputs internally terminated to 50 Ω when deselected. This eliminates the need for external 50 Ω resistors on unused paths, simplifying PCB layout and improving system-level VSWR stability during switching transitions-critical in basestation antenna arrays and filter banks.
What control voltage levels are valid for the A/B/C inputs of the HMC183QS24E?
The HMC183QS24E accepts negative logic control voltages referenced to Vee (-5 V): HIGH state is defined as -5.0 V to -4.2 V (with 5 µA typical input current), and LOW state is 0 V to -3.0 V (with 70 µA typical input current). Control signals must be driven from a -5 V referenced source; TTL or CMOS logic cannot drive these inputs directly without level translation.
Is the HMC183QS24E pin-compatible with the HMC253QS24?
No. Although both use QSOP-24 packages, the HMC183QS24E and HMC253QS24 have different pinouts and bias architectures: HMC183QS24E uses -5 V Vee and integrated 3:8 decoder (3 control lines), while HMC253QS24 uses +5 V Vdd and requires 8 independent control lines. PCB redesign and schematic changes are required for substitution.
What is the thermal operating range for the HMC183QS24E?
The HMC183QS24E is rated for operation from -40°C to +85°C ambient temperature. It is qualified per MSL1 moisture sensitivity level and supports peak reflow temperatures up to 260°C (RoHS-compliant version). This range meets industrial and outdoor basestation environmental requirements, including uncontrolled cabinet deployments in cellular macrocells.
