Product details
Overview
105143-HMC435AMS8G from Analog Devices is a non-reflective GaAs MESFET SPDT RF switch operating from DC to 4 GHz, delivering 0.8 dB typical insertion loss at 2.5 GHz, 62 dB isolation at 1 GHz, and +54 dBm input IP3. It features single positive 0/+5 V control, MSOP-8G package with exposed ground paddle, and is used in cellular/3G/WiMAX/4G basestation front-ends.
For engineers reviewing the 105143-HMC435AMS8G datasheet, 105143-HMC435AMS8G pinout, 105143-HMC435AMS8G application, or 105143-HMC435AMS8G equivalent, key selection criteria include isolation vs. frequency, P1dB compression (+30 dBm), thermal resistance (75 °C/W), and non-reflective termination behavior under RF switching.
Technical Context
This SPDT switch uses GaAs MESFET technology with integrated bias circuitry enabling single-supply 0/+5 V control and low 5 µA quiescent current per control line. Its non-reflective architecture terminates off-state ports into 50 Ω, minimizing signal reflection during switching transitions.
The device operates across -40°C to +85°C with ESD Class 1A sensitivity and requires DC blocking capacitors at RFC, RF1, and RF2. Thermal design mandates soldering pins 3, 5, 8 and the exposed paddle to PCB RF ground to maintain junction temperature ≤150°C under +31 dBm RF input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | DC to 4.0 GHz - supports full WiMAX band (2.3–2.7 GHz) and LTE Band 40 (2.3–2.4 GHz) without external tuning. |
| Insertion Loss | 0.8 dB typ. @ DC–2.5 GHz - enables minimal signal attenuation in transmit/receive path selection for basestation TRX modules. |
| Isolation | 62 dB @ 1 GHz - prevents coupling between antenna paths in diversity or MIMO configurations. |
| Input IP3 | +54 dBm @ 0.5–1.0 GHz - ensures linear operation with two-tone +7 dBm inputs in multi-carrier cellular systems. |
| P1dB Compression | +30 dBm @ 0.5–4.0 GHz - sustains high-power handling up to 1 W peak in WiMAX/4G PA output switching. |
| Switching Speed | 40 ns tRISE/tFALL - supports fast TDD frame switching in time-division duplexed infrastructure radios. |
| Control Voltage | 0/+5 Vdc with ±0.2 V tolerance - compatible with standard CMOS logic drivers without level-shifting circuitry. |
Pinout & Package
Package: MSOP-8G (8-lead mini small outline package) with exposed ground paddle; body size 3.0 × 3.0 mm, footprint area 14.8 mm²; Sn/Pb lead finish; MSL Level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Control Input A | Selects RFC→RF1 path when low (0 V); part of truth table defining SPDT state. |
| 2 (B) | Control Input B | Selects RFC→RF2 path when low (0 V); complementary to Pin 1 for mutually exclusive path activation. |
| 3 (RFC) | Common RF Port | DC-coupled 50 Ω input; requires external DC block; connects to transceiver or PA output. |
| 4 (N/C) | No Connect | Internally unconnected; must be externally grounded per evaluation board layout to reduce parasitic coupling. |
| 5 (RF1) | RF Output 1 | DC-coupled 50 Ω antenna or filter port; terminated in 50 Ω when off (non-reflective mode). |
| 6, 7 (GND) | Ground Terminals | RF ground reference; must be soldered to PCB ground plane; works with exposed paddle for thermal conduction. |
| 8 (RF2) | RF Output 2 | DC-coupled 50 Ω second antenna or diversity path; identical termination behavior to RF1. |
Key Features
| Feature | Design Value |
|---|---|
| Non-reflective architecture | Terminates off-state RF ports into 50 Ω, eliminating signal reflections that cause VSWR spikes and PA instability. |
| Ultra-small MSOP-8G package | 14.8 mm² footprint enables dense RF front-end layouts in compact basestation radio cards and small-cell units. |
| Single positive 0/+5 V control | Eliminates need for negative voltage rails or level shifters-reduces BOM count and simplifies baseband controller interface. |
| High linearity (IP3 = +54 dBm) | Maintains signal fidelity in multi-carrier LTE/WiMAX deployments where intermodulation distortion degrades adjacent channel power ratio. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT RF switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC547LP3E | Wider bandwidth (DC–6 GHz), higher P1dB (+33 dBm), but larger 16-lead QFN package (25 mm²). | Better suited for 5G FR1 (3.3–4.2 GHz) and millimeter-wave test instrumentation requiring extended frequency coverage. | Choose HMC547LP3E when >4 GHz operation or higher power handling is required; accept larger PCB footprint and reflow profile changes. |
| Qorvo QM11036 | Si-based pHEMT, 0.7 dB IL @ 2.6 GHz, 45 dB isolation @ 2.6 GHz, +29 dBm P1dB, 12-lead QFN. | Lower cost alternative for WiMAX/4G CPE where 62 dB isolation is not mandatory and thermal constraints are relaxed. | Choose QM11036 for cost-sensitive consumer-grade radios; verify system-level isolation meets link budget with lower spec. |
Compared with HMC547LP3E and QM11036, the 105143-HMC435AMS8G offers optimal balance of ultra-small size, 62 dB isolation at 1 GHz, and +54 dBm IP3 in a proven MSOP-8G package-making it preferred for space-constrained, high-linearity basestation and test equipment designs.

FAQ
What is the maximum RF input power the 105143-HMC435AMS8G can handle continuously?
The 105143-HMC435AMS8G supports continuous RF input power up to +31 dBm at the RFC port under specified bias conditions (Vctl = 0/+5 Vdc). However, Analog Devices advises against continuous operation above the +30 dBm P1dB point and prohibits "hot switching" above +24 dBm to prevent reliability degradation. Derating applies above 85°C ambient per its 75 °C/W thermal resistance.
Does the 105143-HMC435AMS8G require external DC blocking capacitors?
Yes, the 105143-HMC435AMS8G requires external DC blocking capacitors at all three RF ports (RFC, RF1, RF2) because they are DC-coupled and matched to 50 Ω. The evaluation board (EVAL 105143-HMC435AMS8G) uses 100 pF 0402 capacitors; values must be selected to maintain impedance match across the DC–4 GHz band.
What is the meaning of "non-reflective" in the 105143-HMC435AMS8G datasheet?
"Non-reflective" means the 105143-HMC435AMS8G internally terminates the off-state RF port (e.g., RF1 when RFC→RF2 is active) into a well-matched 50 Ω load. This prevents signal reflection that would otherwise cause VSWR spikes, PA instability, or measurement errors-unlike reflective switches that present high impedance in the off state.
Can the 105143-HMC435AMS8G operate outside the -40°C to +85°C range?
No-the 105143-HMC435AMS8G is characterized and rated for operation only from -40°C to +85°C. While junction temperature may reach 150°C under high RF power, the ambient operating range is strictly limited. Operation outside this range risks parametric shift, increased insertion loss, and potential failure due to thermal stress on the GaAs die or package interfaces.
Is the exposed ground paddle on the 105143-HMC435AMS8G package required to be soldered?
Yes, the exposed ground paddle on the 105143-HMC435AMS8G must be soldered to the PCB RF ground plane. It serves dual functions: providing low-inductance RF grounding critical for isolation and return loss performance, and conducting heat away from the die (thermal resistance 75 °C/W). Omitting paddle soldering violates the absolute maximum ratings and invalidates the +30 dBm P1dB specification.
